Excess spray from outboard on SIB
I didn't think I had a problem until I read a thread from a few days ago re excess spray from outboard (as a first timer thought it was just normal) - so I went and looked at my set-up. I have a 380hd Ali floor Seapro SIB with 30hp 2 stroke tiller outboard. The boat transom height is 15.5 inches and length of outboard (bracket to anti vent plate) is 17inches so anti vent plate is 1.5 inch lower than bottom of transom.
Having the boat out for the first time last month overall went great but had some issues 1) excess spray, some of which coming over transom 2) on occasion had to fight the tiller on turns (is this normal?) 3) when loaded (2 adults and 3 teenagers) on occasion boat would reduce speed, floor would lift and boat would come off plane. Tried different trim and passenger positions which did seem to help. I did post re 3rd issue and after replies came to the conclusion that it was a keel pressure issue as only had 0.2 bar instead of 0.45 bar which was causing air to get under keel and lift the floor.
My concern now is as follows: Is the outboard too low and do I really need to raise it. Will this resolve the spray problem and poss have caused the other problems too. By raising the outboard will it dramatically improve situation re spray and give better performance or just slightly improve it? Reason I ask, I have drilled holes etc and don't really want to drill more. Boat seems to perform well so wondering if it's worth worrying about the set-up. Would be keen to hear from other Sibbers with your experience or thoughts on this one. Cheers Chris
