Slow pickup on merc 200
Looking for advice on an issue I have with an old merc 200hp
Engine is running fine when boat is running with 2 pax onboard and knocking out about 55mph at 6000rpm on a 21p prop. Pick up and response seem fine (other than a bit of prop slip).
However, if I try towing a skier or even the ringo's, the engine seems to struggle to knock out the rpm at the hole shot.
i have tried several props, all with the same result.
fuel lines and primer bulb are all new and no kinks in the line.
Is it worth renewing the fuel pump or am I looking in the wrong direction?
The less time I have to work, the more I get done !!!
