Deteriorating hole shot

The hole shot on my 2000 Yamaha 130 2 stroke is getting slower and slower. Top end is about the same but the hole shot is definitely worst. Any suggestions as where to start looking?

Prop wear? Extra weight (water) in bote?

Weight hasn’t changed much, and I assume OE is Old Engine, which is probably right.


OE = Compression check needed… Can try and run expensive high octane fuels too if you think it will help/compare. May even have some blocked fuel filters?? slowing down the fuel feed…
