I have the same engine on my Alumacraft Competitor. Tiller (I had it converted). The boat does 52 mph empty.

The power trim unit is expensive to replace. Luckily I horse traded boots for my new power trim when mine went.

If it runs good and the compression numbers add up there is not much else to check. Anything can go bad at any time and there is no way to tell when. They made a 70 hp, 80 hp and 90 hp engine in those series. My buddy had a 70 and upgraded the power head to a 90 when his 70 blew up.
