bouncing outdrive

[rigidy]

Trying not to sound to stupid, I've gone through almost everything on this 74, Sea Ray 240SRV (fixed/replaced, cleaned, etc.) put it in the water lever it into reverse & the outdrive comes out of the water, prop spinning, water spinning everywhere, like it's not locked in place somehow, also when tilting up/down the outdrive raises/lowers very fast & does'nt slow towards the end of the max. tilt range, wondering if these two things could be connected & how to fix, any help appreciated, next time this thing goes to the harbour & does'nt function I swear it's gonna be bonfire wood;.

Re: bouncing outdrive

What drive do you have?

Re: bouncing outdrive

Thanx for responding, it says OMC & the guy I bought it from gave me a reciept for work done to the outdrive that says Volvo Penta, it's on a Ford 302 motor & the model# on the outdrive is 981061, just to make it a little more clear on whats happenning everything seems fine till I put it in gear, when I do that it's ok till I give it some throttle as soon as I do the outdrive lifts out of the water, am I missing something that could hold it in place like a switch somewhere that locks it into place. all your responces greatly appreciated.

Re: bouncing outdrive

On the port side of the drive is the tilt clutch. Your problem exists in there. The clutch plates are slipping for some reason. I personally never had a problem with mine. What I do know is that this area is a pain to keep sealed and you more than likely have water leaking in there and or no oil. Take the cover off and have a look.

Re: bouncing outdrive

Your awsome for spending the time giving advise like this, something I'm definetly not used to, I'll check it out & let you know what happened. THANK YOU.

Re: bouncing outdrive

It it turns out to be a Volvo Penta SP drive there's a spring loaded clip that if it's not engaged will cause the unit to tilt up in reverse.

Re: bouncing outdrive

Well...if the drive number is indeed 981061 then its an OMC. A bunch of conflicting info here. Might be worth posting a picture of the drive.

Re: bouncing outdrive

I tried to load a pict. but keeps saying it's to big, I did (under the paint) discover an outlined OMC on top of the outdrive right by the fluid level check so it's definetly OMC, I removed the plate off the tilt gearbox ? well whatever it's called & you were right it had about 1/2 cup of milky white goop in it I cleaned it out real good , blew it out with compressed air, there's some large washer like plates that fit onto a metal mold of the same shape but opposite sex, seems that if those plates slip out of the metal gear thing they sit in something's gonna slip or not work at all almost like there should be a spring of some sort between the cover & the plates to keep them pushed into the area there suppose to sit in, hope I'm explaining this right, if there is'nt a spring in there what's suppose to keep them from slipping out of the slots they sit in to enguage the tilt ? I think it might be called the tilt clutch ?, thanx again guys/

Re: bouncing outdrive

It's kinda like a motorcycle clutch. There is a snap ring that holds it together and a "spring" washer that looks kinda cone shape but mostly flat. If the snap ring is gone or the washer is gone there is nothing to maintain pressure on the clutch plates. Does the drive go up and down without problems?

Re: bouncing outdrive

Yes the tilt goes up & down but when going down it really drops the outdrive down fast almost scary fast like it's gonna break something when it stops, seems like the switch should should be able to increase or decrease the speed of the thing when it's going up or down, I tried lifting up on the outdrive when it is down & cant budge it so I baffled by why it lifts out of the water when given some throttle, I've been reading the OMC stern drive manuel & talked to the guy at the omc dealer here in town, he wants me to bring in the clutch pak which I dont want to take off if I can help it there is a retainer on each side of the clutch pak & nothing seems loose (looks like the pict. in the manuel, The manuel says the 1st thing to check when one has problems with tilt is the "hammer blow coupling", do you know if this part would cause the described problem (outdrive jumping out of the water when put in gear) also would the area the clutch pak sits in being dry exept for some milky stuff cause this ? the dude at the omc store advised me a clutch pak is around 500 if thats the case my boating days are over. thanx for the help.

Re: bouncing outdrive

I dont want you guys to get thrown of the origonal (main ) problem which is keeping the drive in the water when the boat is in gear, I'm pretty sure the clutch plates are ok because it goes in & out of gear fine & foreward & reverse fine maybe I'm wrong Idonno just seems like there would be something that locks it in place when down in a certian position. I know I could strap it down with a rope going from one side of the transom to the other, hell it'de probably work long enough to catch the last 2 or 3 days of the fishing season while it;'s here. oh wait a min. would'nt be able to steer.

Re: bouncing outdrive

When you lower the drive, you need to do it in a few steps. Don't just hold down the button and let it slam down. Very Very Very hard on the drive and the clutch you are having problems with! Push on the button in spurts like punching a doorbell.

Yeah, great advice, the old OMCs (mine included) really slam down if you just hold the button.

Re: bouncing outdrive

Ok thanx for the advice, I went out to the boat today got behind the outdrive & was able to lift it up, not easy but I did lift it, if that helps diagnose anything.

SOUNDS LIKE TO ME THE CLUTCH PACK IS GOING OUT... THEY SIT ON THE END OF THE ELECTIC MOTOR SHAFT IN THE TRANSOM OF THE BOAT.

Re: bouncing outdrive

thanx again for the advice, turns out your right about the clutch pak but rather than invest any more in something that things seem to be breaking every time I look at it what I did is drilled a hole through this & that & I'm just gonna lower the outdrive by hand when I get to the launch ramp & stick a metal rod through each side with a cotter pin & call it good, may not look to kool doing it but at this point I'm gonna milk her for all she'se got on 0 budjet. Sure wish I still had my Wellcraft, Dam good boat.

Re: bouncing outdrive

I had this same problem. It's the clutch plates that are worn out. I didn't want to spend the money on a new clutch pack either (at this point), so I put it all back together and drilled a small hole through the clutch pack itself & drove a pin through it to hold all the plates together. I stuff the clutch housing with marine grease to keep things lubed even when water seeps in & it works perfectly. Obviously this makes the whole purpose of a clutch being there useless (ie, if you hit something you're more likely to break something since there is no clutch to allow the drive to swing up under blow pressure).

Someday I'd really like to replace the clutch pack back to original so I have that peace of mind again, but for now it gets me going again without the drive flying up in reverse.

Also, if no one else has said it to you yet, don't ever tilt that drive up while the motor is running! Always have it all the way down before starting the motor.

Re: bouncing outdrive

Just following the post. I think I am missing something.

If your outdrive goes up and down, right now, then there should be enough "grab" in the clutch pack to keep it down in reverse. Meaning, if it has enough to lift that heavy leg it should be enough to hold it down under reverse idle.

It sounds like you keep this boat in the water (mooring/slip/etc).
Did the tilt work, and the leg stay down, then develop the problem with staying down? Once that problem occured, did the tilt up fail?

The only reason I am asking those specific questions is because that would be perfect and exact symptoms of the following scenario.

If you had been using the tilt down switch in the one motion , from up all the way down, and have allowed it to slam home, you may have knocked the end retaining cap out of the shaft. You may have lost the worm gear. This would also allow copious amounts of water into the clutch pack.

Been there, done that. Learned and moved on.

If you didn't lose the retainer, and it is only that water has affected the clutches, then you can fix this and MAYBE "rejuevenate" the clutch pack.

If you go with some sort of HARD rigging the clutch or fixing a stop on the quadrant, you are sacrificing an important safety feature. That clutch pack is your release should you hit something. It is only supposed to take 100 something pounds of lift to force the leg up, slipping those clutches.

Normally I'd agree with your logic, but in this case I have experience & it does indeed continue to work on dry land, but then fail in the water. I think it could be a combination of temperature, water infusion & perhaps just the quick torque of the propulsion. I would even be able to drive all the way to the lake with the drive supported tilted up only to have it refuse to lift after running the water for awhile (tilt motor spins the clutches, but the clutches don't grip).

I totally agree about the lack of a safety mechanism when you fuse the pack together & would definitely recommend not doing it if you can afford the clutch pack. The costs to repair the boat/drive after hitting something is surely much more than the cost of a clutch pack!

Re: bouncing outdrive

Yes I also agree with the fact that it is risky pinning the drive in down position & chansing hitting something in the water & if & when I can fix the clutch pack properly I will but with my funds the way they are now & 2 weeks left till the end of the best fishing season Ive seen here in a long time + the fact that in 25 yrs on the water I've never hit anything that caused my outdrive to "lift" up & go over (knock on wood) never use auto pilot & dont drive at night & have a 9' Zodiac w/4hp for backup if that thing rips the whole transom of her I'll comfortably slide onto the Zodiac grab what I can mark the spot on my gps (handheld) & que sara sara. you guys have been great with your advise though & right 99% of the time, I'm glad I found this site & look 4ward to chatting in the future. btw I'm about to purchass a 16' Glastron w/115 hp Evenrude attached to it & trailer for 300.00$ so I'm sure there will be a few things I'll need help with, at this price I'm sure of it, Thanx Again.
