Good time of year to go through your ski boat engines and components that make it run properly. Recently I pulled down a GT-40 that had been thoroughly abused. one of the complaints was it wont make power........Fuel Contamination is the biggest culprit in the ski world. Many a skier boat fails miserably because they refuse to practice good clean fueling. Commonly I see fuel cans on skiers docks with a rag or paper towel hanging out of the spout, or worse yet no cover at all sitting out in the rain and or dirt.
The fuel systems on these motors can only digest so much crap before the either clog up with debris or just rust up.
This Fuel system had no chance to be cleaned up and reused, Replacement can be costly. Keep you fuel practices sound and change your filters regularly!
And many skier's wonder why the tournament boat skis harder then their practice boat!
Hobby Boats can be expensive when the hobbyist is limited on their own skill and expertise.
