Don, If I have any future issues with the Boyesen's I'll contact you for the ones you were talking about. I'm interested in hearing about the on the water results when you install some. Please keep us informed as always and thanks again for the great amount of help you provide. If it weren't for this site with it's forums of knowledgeable pros like you, I would know zero about my how my motor is supposed to work or be cared for.
