Curious if anyone can’t point me in the direction of what else to check. It seems everyone with the AR195 is topping out around 46-49mph. My boat will not go above 35mph. It is running WOT at 7450 rpm which seems to be on par with Yamaha 7500 spec. I just put new iridium spark plugs in it. Last year it got the solas impeller, lucky cone and upgraded air filter. I run 93 premium fuel and I have checked the speed with phone gps it is topping out at 35 mph. Located in Ohio so altitude shouldn’t be a factor. I wet slip the boat can the sludge really cost me close to 15mph top end? Any thing else to check?
