New Motor Trouble Out of The Box

[Chesapeake Explorer]

Now its not peanuts or monkeys but you may smile , take sidelong glances and say I told you so's ..Ok got my new 2004 Yamaha 90 2 stroke rigged on the Boston Whaler New 704 control Key switch..ready to gpo and when shifting into forward the prop will not lock up. turn it to the left and its locked, turn it right it click clicks off the dog . In Reverse it locks up, Nutral is Ok. Yes I know how to adjust the controlas..grin! Have had motor cables on and on plenty of times. Undoing the shift cable and manually pushing the shift all the way to the stop (yes turning the prop) and still not positive lock up. I figured that the motor was not running .. needs the crank turning,, burrs ect new.. So I fired her up tonight for the first time. Ideled a good 15 minutes and went out. shifted reverse and good to go, nutral no problem ..would it click in forward.. No engaged good to go. went out powerhead seemed running rough a bit vibration, good motor sound deep throated kind of sound, keeping speed down below 3000 RPM got up on plane and felt a vibration the hole time. Motor is on tight, prop on correct at 25ft lbs on a torque wrench. Just does not feel right to me. ran about 15 minutes back in. No grinding noises but the vibration is not right. Back in checked to see if lower unit is locking up right.. Reverse again good, nutral good, forward, still not locking up when you turn prop to right. Now theres no grinding noise or clicking when running.. I suspect that the lower unit is not shimmed properly.. from get go.or is more break in needed.. I dont think so.Motor is set so cativation plate is about 1/2 inch below hull. No dings on prop. Its a Yamaha 13 1/4 X 17.<br />Should I give another test run or take it back to the dealer. Bought new in the crate its rigged now and they will have to deal with it on the boat.Yea I know ..when they get to it...

Re: New Motor Trouble Out of The Box

I am suspecting I am right.<br /> a dealer that sells a motor out of the box without the proper PDI should lose the franchise.<br /> sounds like an ed's marine special.<br /> good luck getting any warrenty work with it.<br /> the descrition you gave of the lower unit is normal. <br /> hunt the next rabbit.<br /> <br />that is how it was designed to work.<br /> tear it up and no one will warrenty it, especially when the primary ID runs back to ED's marine, unless ED's does it.

Re: New Motor Trouble Out of The Box

Rodbolt thanks for that info. Did not know about that prop turning in Forward like that..Thought it was not locking up. Saw it right off the bat after hooking up controls. Figured dog was not fully engaging, my old evinrude locked up in F and R. I was expecting a clickity click on the first shift into F. But of course it went in . There was some vibration though..Motor has about 20 minutes on it..New motor jitters I think cause I "thought" something was wrong. I did have a problem with the new Yamaha fuel line. The ends fit the motor fine, they dont fit the Tempo brass portable gas tank fittings , They dont latch in good. I could not get the Yamaha bulb to pump up hard.I ran the boat with a OMC fitting on the tank and old fuel line and a new Original Yamaha fitting on the motor end of the old fuel line. I tried the Yamaha fuel line with OMC end and Original Yamaha end and it would not pump up as I said. today I put Tempo Yamaha fittings on the tanks and the fuel line. They are a bit bigger in size then the OMC. My old engine would start, idel out a channel a 1/3 mile then when I opened it it up, vibrate, shudder then clear and run fine.. I fiqured it was the VRO but..Hmmm air leak maybe on the old line..fuel restriction.. both no good I know. I wondered about that fuel line I does not leak gas however. I will bed the new motor with a bit of 3 M adhesive and seal all motor bolts also. I think the new motor is OK

Re: New Motor Trouble Out of The Box

most likly its ok. you do need to check the oil contols and bleed the oiling system per the service manual. occasionally its wrong out of the box. my opinion is tempo products are junk. use the yamaha stuff. try to find a copy of the PDI sheet and go over it as per the instructions. also a factory service manual and the procedures for maint in section 3 are handy.

Re: New Motor Trouble Out of The Box

Rodbolt.. that 75 dollar service manual speaks of bleeding the oil pump..but theres no info! Belive it or not! I loosened the phillips/cross screw with the red fiber washer that sits at a 45 degreee angle so you can get to it and bleed this pump. oil flowed and I screwed it tight allowing no air in..but is the motor supposed to be running? The tube running back up to the tank has oil to the tank level also..looks like its suckn oil. pityful service manual!<br /><br /><br />i have asked several questions here..<br /><br /><br />I appriciate your advice and knowledge shared, I guess you are a dealer. Its above and beyond of you to post and help folks as its understood you dont have to say a peep about anything, your advice is sought as you have the expertise thanks!

Re: New Motor Trouble Out of The Box

hello<br /> I agree with you on the manual sometimes. ok most times.<br /> I usually crack the bleed screw with the moror running and the link rod disconnected and the arm at the WOT position. however for years all we did was crack the bleeder with the tank full. now I usually find the longest and easiest oil line and remove it and watch the oil flow from it with the engine idling and the pump arm at WOT position to insure its flowing oil.<br /> that 90 is about bullet proff and will tolerate a lot as long as your premixing during breakin. biggest thing I like to see is to mark the tank and track the gallons of fuel used and calculate is the pump working as designed after several tanks or when breakin is done before switching to plain gas in the tank.<br /> I am not a dealer.<br /> I am a tech that works for several dealers, 2 of them happen to be yamaha.<br /> I have also been doing tech work on machinery and such for about 30 years now. some techs do it 30 years and make the same mistakes for 29 of them some of them enjoy learning and doing it right.<br /> proplem is ya never know which ya have until its done.<br /> so ask any thing ya like and most here will respond. anything I know Ill post.

Re: New Motor Trouble Out of The Box

Got 4 hours now on the motor, bleeded the oil pump. saw some instructions in the manual about oil volume and a graduated cylinder to measure in three minutes, Oil pump is going good,Using oil from the tank, moved the trim pin back a hole so its in contact with the motor trimmed down.vibration at 2000 is not so bad now , had hand on cowl at idel running in gear and 3000 rmp not so bad vibration. Motor runs strong ran 11 miles up river and back today, fianally could go flat out after the first two hours break in, still ran flat out only a minute at a time..manual says not more then 5 then let cool. motor is more responsive at low speeds. Its easy to start and idles good..better gas milage then the old Evinrude about 4 gallons used for a 24 mile round trip ,No bad noises from this motor ( grinding whining ect) , got a throaty sound I belive it will prove to be a Champ! New motor jitters and needing some break in is all it needed plus some TLC on all the setting up and break in witch it got.. Thanks Rodbolt for your help! Will give a report with about 20 hours on this same thread. I belive I will wear egg on my face 'New motor Trouble out of the Crate" I will be laughing about this in time I'm sure.

Re: New Motor Trouble Out of The Box

Forgot to say I marked the tank and will measure gallons of gas used VS oz of oil. It dropped two inches today . I did not fill the tenk to the max..left about 3 inches headway to the top to aloow for tilting the motor. With 50-1 its 48 gallons gas to a gallon of oil . With injection the oil gallon will go much father as at WOT its about 50-1 and at Idel its about 100-1. Before running stright gas I will check the output as per Rodbolts advice.
