How big a motor?

[chris thomas]

I am the one with the 1989 Starcraft Islander. Is a cuddy, aluminum, rated at 150 hp max, weighs about 1250 minus motor, and add 600 lbs max for people and stuff. I use it for light ocean work and playing in the lakes. No skiing. It currently has a 140 Evinrude x-long shaft. <br /><br />I looked at the Honda page and it looks like their 90 should push it in the low 30 mph range. I think a 70hp is to small. Does any one has any experience with this set up.
