Yeah, I really need to come up with a happier name for the darn ol' thing.

It ain't even mine, and it's causin' me some ridiculous frustration.

My buddy had purchased a 16' Alumacraft with a 1982 Evinrude 35 HP on it. Yeah, it was old; yeah, the boat needed some work; and yeah, it was sold at a remarkably great price. We knew there were issues, because the engine had completely conked out on one of the trips that the original owner and I had taken on a river... since that day, the boat wasn't fixed or nothin' until my other friend bought it.

We thought that the hub was broken in the engine, nah. It would spin in reverse, but not forward, and finally diagnosed that the differential had broken some how. Luckily we found another 1982 Evinrude E35ECND 35 HP engine on Craigslist but an hour away from the university. We took the lower unit off that and slapped it onto the upper unit of the original.

We smacked on a new prop and restored the hub fixture into the original prop. We gave her a try, still nothin'. We diagnosed it again, only to find that the water pump had somehow gone and melted to nothin'. Luckily, we didn't break anything on the engine block. We purchased a new water pump and got it installed. We had to take the engine up to where we bought the lower unit from, because frankly, in the world of engine repair - we're freshmen. We're die-hard fishermen, but boat repair is not a strong point for us quite yet... We're getting there.

We need your help. This engine would turn over, even though it had some items in her that just would not work right... the key is that she turned over. When we put the engine back on, and put the steering back in, and all the other doo-hickeys all over, we gave her a crank; to no avail. Everything was working ay-OK. We had charged the battery, hell, we even took the one out of the car to make sure. We had replaced the fuel because the old stuff had been sitting in the boat for darn close to two months. We had made sure the ear-muff looking things were over the vents... Still nothin'.

Please, if ya'll got any schematics for the 1982 E35ECND Evinrude 35 HP engine or heck, even just pointers for us, please send them my way. I very much appreciate it.

Thanks for your time, ya'll.

Zach.

Re: The Engine of Doom - Please, Help.

welcome to iboats!

i would suggest you look at "frequently asked questions". there is a lot of info in there..........then when you have ran some of those tests you can ask a more direct question.

if you are saying you have some wiring issues and need schematics here asre some.

you have to scroll down to omc and it says it based on '96 ................but if you have the red plug on your engine then it is the same.

i suggest you get the OEM Evinrude service manual for that motor, and make it your best friend for about a week, then test the motor again.

The OMC manual is a good suggestion. This motor likely has multiple problems to troubleshoot.
1. Check the compression. They should be within 10% of one another.
2. Check the spark on all cylinders.
3. The carb probably needs cleaning, since it sounds like the motor has sat around.
