Post motor replacement questions?
right now i have a 9 horse go devil and im not getting the rpms needed to plain my 1448 which other people say should happen....do i take my motor and have it modded with a cam and bore it .30 over mill the heads and add exhaust or put another motor on? if i put another motor on i know i have to watch the shaft size but what if i put a 16 horse on that frame? i know i need to chang the prop as well but will the shaft and the rest of the fram hold up? and does any one know of a light sturdy alluminum i can get somewhere to put in for a floor instead of the wooden floor i have now? thanks

I only turn 3250, 23 Gdlt with me and my dad and gear. So for a 9 I guess that's about right. And my exhaust turns red too that's normal. I'm not a motor head like some of the guys on here. Pm boat dr.

Critch5, I used .080 gauge alum for the floor in my 1648 Grizzly, plenty sturdy. To make it level I used some U channel bracket down the middle of the boat. I used ss screws onto the ribs, probably rivets would have been better. I do suggest some closed cell flotation (I think Lowe's has it) under the floor and between the ribs, this will make it a snug fit and ward off the cold and make it quiet.

A 23 van. Will fit on that frame with a new u-joint, call GD to make sure though.
