1972 Evinrude 65 triumph SANK

[jagboy69]

I'm extremely happy to have found this amazing source of info for these old motors.. and that I THANK YOU!

As everyone knows, no boat is ever "Free" I see a boat sunk upside down at a dock and start asking questions... It went, it you can get it out of here, it's yours! What a deal. Turns out it was a 1972 15ft del-magic with a 1972 Evinrude triumph 65hp with a fine trailer. The boat was underwater for almost a month. I pulled it out and went to work on the engine within minutes of getting it out of the drink. SO far, I've cleaned out the starter and shes good to go. I've gotten the water out of the engine and have cycled about a gallon of marvel mystery oil through it. The engine has compression numbers ranging from 112-125 so that pleases me also. Now comes the fun part is the electrical stuff. I've opened up the power pack and drained it, dried it out and sprayed with electrical cleaner. There is NO CORROSION on anything. Gotta love freshwater! Same for the stator. The bad news, when it sank the battery shorted out and fried the starter solenoid, the main terminal block on the side of the engine and also the ignition switch on the remote. (I have the 3 button gear selector working like new also) That's a little background so here's my questions.

1. Any chance the coils are still good? Is there a way to test them off the engine?
2. What about the power pack? It looks clean and dry, they're sealed in some kind of goo. Any test for it?
3. Would the stator survive a dunking like this?
4. How about the gear selector solenoid(s) in the case? I've read here they are impossible to find? Is there a way to test without electrifying the ignition system? (remember bad ignition sw with melted wires)
5. What about the shorted battery? Stray volts going to anything else that might make this motor not worth messing with?

Mechanically I would say this engine is in fine shape. Electrically, it's a lesson to others. If you leave your boat unattended, even if you think it would never sink in a million years. INSTALL A BATTERY KILL SWITCH!!! I would not be looking at the extensive damage if the PO had done so.

Any advice is really appreciated. Thanks for reading my saga. ;-)

Jason,

IT sounds if you covered alot of bases with everything you have done.

I ran across a deal like that with a newer 1990 model.

My suggestion is clean averything you possilbly can make sure everything is dry. Fix what is broken and use the parts that you have and put it back together.

Coils - as long as they are not crack or damaged in anyway they are fine.
Power pack - is a 50-50 chance it will work it is sealed
Stator just a bunch of magnets with windings on them. Make sure it is clean and no broken windings.

Now 4 don't know nything about those selectors

5 Battery all the juice was drained out in about 15mins on that battery.

Good luck.

You are going to need a LOT of good luck. Not meaning to be a pessimist, but the bearings are probably all etched in that motor. If so, they will soon fail. You can tear it down and inspect it now before you spend a bunch of money or you can wait to see just how lucky you really are.

The shift solenoids are the least of your worries. Water can't get to them because they are immersed in oil in the lower unit.

Re: 1972 Evinrude 65 triumph SANK

Thanks guys for the encouraging words and warnings. I'll take my chances on the bearings. I've ordered the terminal block, ignition switch, starter solenoid and the rectifier. (found blown wires on it today) Also tons of new terminals for the trashed wire ends.

I did screw the pooch and in my haste, I removed that 3 button electric switch and forgot to write down what wires went where! DOH! and I know better. Anyone know what color wires go where to the 5 spades under the gear selector switch? I am on the hunt for a free wiring diagram..... I'm sure one exists.

glad to be aboard, thanks!

ONE WEEK LATER!!!!

It's ALIVE, thanks to the help of Frank my hero and others here.
Check it out!!! http://www.youtube.com/watch?v=R0YHpFxf7V8

Turns out the coils, the stator and the powerpack survived. I removed the cover each day on the motor and allowed it to cook in the hot texas sun. In the end I had to rewire the remote box due to cooked wires from shorting out. Also the rectifier red wire fried along with the red wires for the starter solenoid. Today I checked for spark and R2'd the gear box oil. It fired the first time! I'm not out of the woods yet, but you guys are some of the smartest folks I've come across in awhile. With that I say a BIG THANK YOU! I'd be happy to pass on what I've learned to others here. Just pm me and I'll do what I can to give back to the board.

Cool. Post some more pics!

If you replaced the gear case oil and did not refill with BRP Premium Blend (Type C) or an eqivalent oil, go find the right oil, re-drain and replace the gear oil. Do not use High Vis oil in it.

If you have to replace the terminals on any of the wiring the goes to the powerpack, you will have to get them from a BRP dealer - the necks on them are longer than standard terminals.

F_R has forgotten more about these motors than most of us will ever know, so take his advice to heart - don't spend a lot of money on this motor. If it runs after a "minor money attack," fine, but don't go overboard. Further, 112 psi is pretty low for an OMC "triple." When new, they are about 150 psi. I think what both F_R and I are getting at, is that the motor might be serviceable for a little while, but probably not long.

At whatever point the powerhead fails, you can always part the motor out. If you have a working remote control, a functional gear box and midsection wiring harness, you have a minimum of a few hundred dollars worth of income towards your next motor.

Sorry to be less than overly enthusiastic, but this forum is about help and part of helping you is to make sure that we are realistic in our answers.

Re: 1972 Evinrude 65 triumph SANK

Is this the same motor that you are discussing in a thread about gear oil?

Re: 1972 Evinrude 65 triumph SANK

Yup, same motor.

Re: 1972 Evinrude 65 triumph SANK

Ah ... Go back to the other thread and see the OMC Service Bulletin on gear oils. I think it answers the issue of Type C oils v. Hi-Vis. I would want to get the right oil in the gearcase, to see if it shifts and better, before moving on to other issues.
