done more research i was wrong . 1.98 is a lower gear ratio my boat with a 1.84 and a 14.5 diameter 20 pitch rampage prop will turn 5100rpm wich is a little high. so this guy has the 1.98 ratio outdrive and has a 5blade mercruiser high 5, 23 pitch prop. will this work out ok. or not. i can get it all for 450 bucks
