I need some used engine advice. Aside from compression checking, lower unit check and cosmetic check what else shoed be checked on 1996 Evinrude 115? Under normal conditions how many hours will such an engine last? thanks for any info. JIM

ALWAYS make sure your "lower unit" is in good shape. Nothing can ruin a man's day like a lower unit that has been abused by running it into foreign matter, or dinged up by ramming it into unknown areas.

Hi, Jim -
Compression checking and (lower unit check -I assume you pulled the oil plug from the skeg bottom to inspect the oil? If milkshake, then water is mixed in with gear oil, not a good thing). Quick checks, I'd also look for salt corrosion residue on the engine and ower unit. IF freshwater use only engine, that is better than salt use. I'd guess low hour use for a 5 year old motor is probably 150-200 hours, and if well maintained with those hours I'd guess will go twice that with normal use, with few if any problems. Are the hours documented by say an hour gauge? or just a guess? Are you buying this engine or have time to seriously inspect? If time is on your side, you may consider pulling the lower unit off and looking at the water pump, too. Easy job that will tell a lot about use.The <90HP> block is a good one, and I'll bet that 115 is the same block with bigger carbs. Hope that helps, Best - Mav

jhuiv, thanks for the input. I know lower unit repair is costly, even more so to replace. JimU

2 things:1) Have the lower unit pressure and vacuum tested. Someone trying to sell a motor with a bad lower unit may be smart enough to change the oil. 2) Sea Trial, Sea Trial, Sea Trial. Nothing tells you more about how a motor might run than running it. There are lots of motors with good compression, lower units and paint jobs that are plagued with electrical or fuel system bugaboos. Find out why the owner is selling such a "new" engine. All that said, it may be a great deal with many years left in it. I'm running a pair of '79 Johnsons that run like new. Ok, that was more than 2 things.
