Re: Can I put a Sail Pro propeller on my 2004 Tohatsu 6hp?
Yes. The props for the Tohatsu/Nissan 4/5/6 all interchange. The 3-blade HT prop for the UL Sail Pro works fine. We have rigged a lot of these with great success.
The really dramatic low-speed thrust gains are even more evident on the 8/9.8 when using a 4-blade HT prop. That's the setup on my 7,000-pound sailboat (9.8 with 5-pitch 4-blade HT prop). Keep in mind that if your sailboat is heavy, the 1-cylinder 6 will have limits.
