Probably a stupid I/O Mercruiser Trans Question

[BarryT]

I have a very old 1972 Mercruise I/O. Its is a 215HP (ford 302) And it is a 215E (electric Shift) transmission. In my manual it mentions changing the transmission fluid, but does not show a location to drain and or refill. Does it even use tranny fluid (the manual covers a ton of engines and drives systems)? I read that with inboard out board mtotrs/drives that it probably just has the drive lube and engine oil. I would appreciate some help. I am awfully confused.


Thanks ahead of time,
Barry

Head up to the Adults Only sticky at the top of this forum. Go to the service manual links and look at manual #1. It's the OEM manual, and the best manual to cover your engine and transmission.

Re: Probably a stupid I/O Mercruiser Trans Question

Thats the manual I have. It shows a lubrication chart that is generalized for all models. It lists changing the tranny fluid there. I looks through the entire lubrcation table of contents and see no mention of tranny fluid change, just outdrive lube.

Anyone? I hope some one knows. I have the mercury oem manual and I am very very confused. Anyone fimiliar with the 215E drive system?

Check with a shop, I have not run across an electric shift MC but I know the OMC electric shifts take a special oil that is lighter weight (thinner viscosity).

What kind of boat is this in ?
What Outdrive ?
How long have you had this boat ?

Re: Probably a stupid I/O Mercruiser Trans Question

The drive is a Mercruise 215E (electric shift). It is bolted to a Mercruise Ford 302. It was made in 1972. The OEM manual available on this site doesn't say it takes a different oil. It is vague but I believe it says "all" mercruise oudrives take Quicksilver "SUPER DUTY" Gear oil Part No. C-92-52650. It seems to be the same as every other drive in the OEM manual. The issue I am having is all the Gear Oil I looked at says "DO NOT USE in OMC electric shift outdrives" Well I have a a Mercruiser electric shift out drive, but it is still an electric shift. I am very confused. I would appreciate any help. Oh yeah the two marine places here know nothing about this drive and I do not trust their input.


Good news though! I did have three expansion plugs blow this winter because the boat wasn't winterized by the previous owner. Well I ran it for about 3.5 hours on the old oil then did an oil change. The oil looks about 4 years old (witch it is), but 0 water. I think I just barely ducted that bullet.

Re: Probably a stupid I/O Mercruiser Trans Question

Sorry Barry,
I got confused. You said Mercruiser then "OMC" outdrive.
Far as I know any/all Mercruiser O.D. uses that lube.
Don't know OMC ?

Re: Probably a stupid I/O Mercruiser Trans Question

Sorry, about the confusion the gear lube that quicksilver sells says DO NOT USE IN OMC electric sift outdrives. I have a mercruiser out drive, but I got nervouse because mine is also an electric sift. In the store I havent seen any SUPER DUTY gear lube just premium and high performance. So witch do I use?

Re: Probably a stupid I/O Mercruiser Trans Question

Does your boat actually have a transmission between the engine and transom inside the boat?

Re: Probably a stupid I/O Mercruiser Trans Question

Did some investigating and it looks like that package uses the borg warner transmission between the engine and drive (inside the boat).You will have to look for the drain plug though.It will either be on the bottom or on the side near the bottom.It should have a dipstick and will need Ford type transmission fluid.Probably 1 1/2 to 2 quarts.In your outdrive you can use either the regular or high performance mercury gear lube.

Re: Probably a stupid I/O Mercruiser Trans Question

If you can't find the drain plug or it is to hard to get to you could always siphon it out the dipstick tube.

Re: Probably a stupid I/O Mercruiser Trans Question

One more time here;To drain the trans fluid you disconnect the hose from the fitting on the lower starboard side of tranny.Then unscrew the fitting and let fluid drain.There may be a spring,washer,and tube inside.There is a slot in the tube that you want facing down when you reinstall.Tube first then washer then spring then fitting.Use dexron ll or type F fluid into dipstick hole.Fill to full line and then after running check if it needs to be topped off.

Re: Probably a stupid I/O Mercruiser Trans Question

Wow thanks for the information! The book just goes over the drive unit and the engine. Wierd I wish it had a picture. I will look for the transmission. Hopefully it is easy to get too. So it should go (when I am looking for it) Engine-bell housing-clutch-transmission-outdrive right? I'm sure I will come bother you guys if I can't find it.

The only thing is when I look at the dissassembly of the drive unit the shift mechanism and gears are at the top of the outdrive. Wouldn;t they be lubricated by the gear oil?

Re: Probably a stupid I/O Mercruiser Trans Question

There is no shift mechanism in the drive.All the shifting takes place in the transmission.That set up with the 302 was only used from 70'-72'.That book is going to be confusing covering different models.Hate to say it but you will be lucky if that electric shift setup even works.They have switches in the throttle to shift it into F-N-R.Than a shift motor on the trans to shift it.Parts would be impossible to get for it.However you may be able to convert it to manual shift.Did you try shifting it when you had it running?

Re: Probably a stupid I/O Mercruiser Trans Question

Yes I did and the transmission does work. It goes clunk and engages both ways. Would the "transmission" be where the spinning shift cable goes into? I would assume so. I will have too look. I can't work on the boat again till Saturday. Hopefully I will have it in the water on monday.

This boat has been the most daunting task I have ever taken on. When I first got it it had 30 gallons of bad gas, then 3 expansion plugs popped (I thought I was Sh** out of luck after that), one exhaust manifold cracked. So I replaced the exhaust manifold and the expansion plugs. Then the usuall fun of starting a engine that sat for 4 years. It fored up with a little starter fluid and purred. Didnt even smoke at all. Then it wouldn't go into gear until I gave the shift mechanism a little love tap. Then the tilt wouldnt work.... I filled it back up with fluid and greased the rams with some dow33 (amazing all purpose grease). Then had my wife hit down while I jumped up and down on the drive. Then I did an oil change and was relieved that cruddy black oil came out, but no signs of water. Today I topped off the power steering and tilt fluid. Saturday it will be getting a battery, drive unit fluid change and transmission fluid change. It should be seaworthy after that I think. The good thing is I have learned so much about boats while restoring this monster.

I also got the 15HP trolling motor running today!

OK found some more info.The electric shift did not use the transmission.There for you will not have any trans fluid to change.Just the gear lube in the drive.Electric shift actually has a clutch like in a car which is electrically operated.Also probably has some type of shift mechanism in the drive to determine forward and reverse.Sorry if I caused you more confusion.Check link above.http://www.perfprotech.com/store/ca...D-302-V-8-1970-1972,3172,model,57571-700.aspx

Awesome! One less thing to do before seeing if it sinks!

Thanks

Re: Probably a stupid I/O Mercruiser Trans Question

I added another link above that has all the engine parts and clutch.It also has parts for the trans which you don't have so don't get confused.You can enlarge the diagram over to the right above the small picture.Good site.I buy parts there all the time.
