In fact I meant 75 HP ( "(" is just above nr. 8 on my keyboard, so I haven't push "shift" before :-) )...
In fact the boat is not full-displacement but a mix which can use different engines.
I know that with 100 HP it goes 15 kt. at maximum and 12 of cruising speed.
I also know that with 150 HP (Steyer) it goes 21 kt. at max and 16 of cruising speed.
Also, when I was building a boat (I bought a kit version, only plastic, many pictures on: Photo Sharing by MyPhotoAlbum :: brodglampo's MyPhotoAlbum Gallery :: Glampo
Now I have 10,5 kts at max and 8 of crusing speed (that's with 100 liter of weater, 200 liter of diesel
and full equipment
plus almost 300kg of persons aboard).
Other problem is that my engine is rated 3000 rpm
max, and TE version (75HP) is rated at 3200. What does it mean? Are that the same basic motors with some add-ons, or completely different cams, pistons etc.?
