have johnson seahorse shortshaft 35hp have just replaced water pump and impellor but when i take the boat out she will rev perfectly but i cant get above walking speed. reving fast or slow doesnt seem to make any difference to speed. it looks to have air bubbles shooting out from prop.<br />have...
Ive put a new impeller in & flushed the system to make sure that theres no blockages & still it wont bring any water through, has anyone outhere got any suggestions, also is there an easy way to take off the gearlever so i can change the pump without having to dismantle the engine.??
