Dave,
The first photo of “Examples of allowable Propeller guards” in the Open Water Sanction Guidelines www.usms.org/.../owgto_sanctions.pdf is of a SwimGuard– Standard - Marine Propeller Guard from MariTech www.maritechind.com/swimguard.html
According to their web site features:
Customized for a perfect fit from the smallest (9.9 hp) to the largest motors.
Can be installed and maintained with boat in the water.
Easy on - No drilling or mounting holes required.
Easy off - Can be taken off and reinstalled quickly, allowing for mission or job specific use.
Note: I have not personally verified MariTech’s claims, but I’ll take them at their word for now.
Let me just say that I like the idea of prop guards enough to have drilled 9 holes in a brand new Yamaha 115 hp motor. The performance loss was unacceptable for the actions that might be required of me during an event. I would love to find an option that worked.
I just had a frank conversation with a gentleman at MariTech and the bottom line is that he said I should expect a 40% drop off the top end. This just won't work for me, but thanks for the link. These guards are great for a venue that can dedicate support vessels to duties
