will not make the wife too happy...
Posted by Brian Richardson on Feb 24 2006
I know ya said - hear from TradBow and Mike Strahan or Phil G
Anyway I've run 'em (18’ LEOs) under outboard power out to sea in some pretty big sauce water late season even snowing (like getting hammered constantly w/ full trashcans of water every few breaths you take). I've also run both soft and hard floors with low HP engines on up to 35 hp.
What I’m going to tell you will not make the wife too happy it sounds like… But 15 HP longshaft and extra longshaft floorless (pretty wet) or hard floored w/ whale tail V and w/ camber (pretty doable still not comfortable) will max out at 11.5 knots on perfect conditions in the 18’ LEO) In other words a slug for any small craft!!!
It sounds like you are taking on the project of an inflatable style party boat so therefore the LION tubes are what you want. I’d go w/ any floor even decent marine plywood or 2x8 boards. No reason whatsoever in your posted hp range to even make it too water dynamic installing it under the frame – Just deck ‘er on top… it’ll never greet the waterline w/ that diameter and an 8 hp. You’ll be looking at 5 knots under exceedingly conservative loading (for the LION).
Kayakers and sculling craft may pass ya up… but hey they might be part of the Party!
