As some on here may recall, last fall I purchased a BBIII from a member on the east coast. The hull was built "to print" and the workmanship was done well. TO BE VERY CLEAR: I am not trashing the original builder. I knew certain mods would need to be done and took that into account during the purchase.
I've done my homework and am well aware of some issues and mods that have been documented here on this forum. Unfortunately a lot of the previous postings, are incomplete and missing pertinent information. I'd appreciate it if some of you will share your experience, so I don't have to reinvent the wheel. Thanks
What I need to do;
(A) trim the corners of the motor well, to allow for full clearance of the motor, throughout the range of tilt.
Seems to be fairly straight forward to mark the interference and trim as needed. Any pictures or dimensions of what worked for you would be appreciated. Again; BBIII w/ 25 hp Yamaha 2 stroke
(B) address the porpoising issue.
Plan is to add wedges on both sponsons. (sp?) Should I also add some wedges along the leading edge of the motor well? Again what has worked for you? Thickness and length of wedge bow to stern ? Does a longer or shorter angle make any difference or is the height of the wedge the only determining factor?
(C) address the issue of water splashing up and into the cockpit from the motor well.
Plan is to add a splash guard around the lower end of the motor. Debating on just where to position it height wise. I am thinking, lower would be better for controlling splash when moving in a forward direction. Yet a higher position would be better to prevent "wash over", when the engine is in full reverse.
Again, would appreciate some feedback on what is working for those that have already addressed these issues.
THANKS
