Location: north central wisconsin | After consideravle thought, I have decided to forgo putting trim tabs on my boat(690 Tiller) and have decided to try one of the hydrofoils. My rig(underpowered with a 90 on a hull rated for 175 if it were a console) gets on plane just fine by myself, ok with another guy, horribly with three guys or two guys and alot of gear. Moving weight around any more than I have is not an option. I am running a 16 pitch power tech prop, and have considered a solas 4 blade 15 pitch as the next best prop to try, though I really don't want to lose the top end speed I have now(37-39 alone, 35-37 with a passenger or two).
So, I am running about 6100 rpm wide open with another guy so that is perfect. I already have trtansom wedges to tuck the motor further beneath the hull for take off. I wonder if I should move the motor up a hole, and perhaps have the prop ventilated before or along with trying the foil.
So, I have been told the Cobra Edge pro series was the 'best' by several folks. Have also heard the doel fin to be a good product.
i guess, i will need to adjust the motor so the fin is out of the water when trimed up to maintain speed and handling, and I can manage that. at this point, I just need to get out of the hole quicker to improve the safety in my rig, and also preserve my nice outboard from the many hazards on the waters I run.
Lastly, I too(like another poster) have noticed maybe a slight decline in top end and hole shot. After inspection I don't have water trapped in the rig. I installed an inline yamaha fuel/water separator when i bought the outboard, but last week when changing the bilge pump, noticed a merc fuel filter as well. I would not have been changed for 4 years at least. Do you think having two filters could be robbing the engine of need fuel flow?
Sorry for all the questions, and thanks in adavance for any and all help.
