Yes it's new to me and the owner before me never used it as he had another boat to use ,so it did sit for a year but it ticks over lovely and I've put fresh fuel in
Hi
I have a honda 25hp 4 stroke that whilst in the water will not go above 4000rpm and we are stuck at 8mph (sat nav) .it's on a pilot dory 15ft boat . It revs all the way to 6000+ with muffs on out the water I've tried trimming it whilst going but no joy
Someone mentioned propeller pitch mine...
