Location: Maine Township, MN | 2011 Yamaha 50TLR stock is a 10-5/8 x 12 aluminum 6H5-45952-00-00. I can't find the same pitch in aftermarket. Am I better off getting another OEM for $130 online? I like this prop, but if I get 3 people in the boat, it's hard to get on plane. I really don't want to sacrifice top speed either. I get about 27 mph (GPS) with 2 people and gear. |

Check ebay. Lots of props there to look into. When you load up with guys and gear, it may pay off to have a prop with lower pitch (like a 10 pitch) so that the motor is operating in an RPM range that creates the best Horsepower and torque to get the boat up and out of the water and moving.
No matter what, when you load up you lose speed, but with the right prop, you can get the boat up and moving, potentially better and faster than your current pitch, just because the motor is at higher RPMs.
Aftermarket props to consider: Solas amita 3. Great prop that is cupped a bit, which, although is aluminum, will flex less and actually act more like a steel prop, without the cost. I believe these will be listed in odd pitches, so an 11 pitch is probably what you would be looking at needing, which could work really well as an overall prop.
With the speed you list, that, I would say is fairly close, but I think you should be able to break 30 mph unless the boat is really heavy or rated much higher than 50hp.

Location: Maine Township, MN | Thanks, I'll look into that. The boat is rated for a 75 but it came in a package with a 50. I checked the Yamaha performance bulletin for the 75 and it didn't seem like it was worth the few thousand more for a couple extra MPH, but now I'm kicking myself wishing I had more power for the holeshot. Oh well, this is just a starter boar for me. Once the wife and I have a couple kids and they get old enough, it will be time for a multispecies glass boat. |
