mercruiser 470 replacement?

A buddy of mine had one in a 17' bow rider .... It did great but that boat had less dead rise and less weight... It could plane a v20 but it would be a dog... Especially loaded heavy in big water.

ok i do load heavy and we do have nasty late afternoon conditions that i try to avoid.

just checking ebay here I see one for 2000+ just seems risky buying used motor i don't know how you reduce that risk.

just gotta wait to see the outcome from boat shop, not get ahead of myself.

Buying any used motor get a compression test before money changes hands.

If you do need an engine, heres al ittle reading for you regarding the 3.7L MERCRUISER engine. As to has anybody done one, I've only seen a handful of V-20's with one swapped in, and I believe tehy all said they were pretty underpowered, and only really suitable for calm waters. Your dropping back in power, and staying close to the same weight. The closest engine in power output to the 470 is the current 4.3L V6 which is the way most go for repowers when they give up on the 3.7L engine.
