He called this afternoon and asked me to take a ride |with him because he couldn't get his boat to plane right. | |We met up at Webster Lake and took it for a ride after checking |everything over - everything seemed to be working, nothing out of |sorts with the hull. | |Got on the water and it's the oddest thing - no matter what trim |position, the boat would porpise (pitch) at speed. Vary the speed and |you'd get a yawing action - trim made no difference. No roll to speak |of. | |All the bolts are tight, properly torgued, the prop is symmetrical, |the skeg on the outboard is straight, keel is straight - no obvious |repairs. | |Any ideas? I'll admit it - I'm stumped. Given the available information, the only thing it *could* be is that the motor is mounted too low. Has it ever planed correctly? If so, what changed... Don't know - it's a used boat, low hours Yamaha. We're going to take it out again this morning. He owns a independant car repair place, so we're all set with lifts and such. I know on my Ranger, I had problems with the FICHT short shaft engine on the 620 based hull - it was never quite right and just playing with the fixed height positioning didn't solve the problems - some would go away, others would show up. It wasn't until I put the jack plate and 25" shaft engine that I could really dial in the engine positioning to solve ALL the problems in addition to gaining 6 inches in length which also helped. |
