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

Hi, Jim -
Compression checking and (lower unit check -I assume you pulled the oil plug from the skeg bottom toinspect the oil?). Those are good things, for sure. Quick checks, I'd also look for salt corrosion residue on the engine and lower 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

Jim, in addition to the checks mentioned above, there are some other things you could do.. Pull the prop to assure that it's not frozen to spline and pull the lower unit and replace the water pump impeller. Added benefit of pulling the lower unit is to make sure drive shaft is not frozen to crank and that all the bolts come out easily! Good insurance in any case to start with a new impeller... as to how many hrs... ??? Good maintenance, good oil and gas etc. is most important.. I put a lot of hrs on all my engines as I'm out on the water virtually every day and sometimes all day and I take quite a few long cruises each year (400 - 600 miles). Last engine I sold was a 1996 Merc 90hp (bought in 1995) which had 2170 hrs. on it... It was in top running condition and never missed a beat! Others may have put more hrs. on engines.. I think Larry G. has some factory rebuild schedule data for commercial engines. But for sure 500 hrs is not a lot if engine has been maintained properly. Happy Whalin'.. Clark
