Lund Fisherman/Yamaha Prop?

[anchor man]

I have a new 1700 Lund Fisherman with a 14 1/4 diameter, 21 pitch Hustler Aluminum prop that came with the Yamaha F150. Does anyone know off hand if this prop should get me into the 5500-6000 max rpm range?

My other question is this, If the prop that came with the new set up doesn't get into the RPM range mentioned in the motor manual(5000-6000) at WOT, should the dealer be responsible in getting a new prop put on that at least gets the motor running correct?

Anchorman,

I'd say you should be good.. if I had to guess I'd say that you'll either need a 21 or 19... depening on how much gear you normally run, among other things.

And as far as the dealer goes.. I would say yes, as long as the rig is new (and not used) the dealer should be responsible for putting the right prop on the boat so that it runs in the range specified by the manufacturer.

Enjoy the boat!

When I bought my new Lund (with a hustler prop) I had a heck of a time getting the RPM's up to 5500. We tried several props before I noticed that the motor was mounted WAY too low on the boat. "I" raised the motor and the RPMS fell in line. I did dispose of the Hustler prop due to vibration at low speeds.

So check your cavitation plate and make sure it appears level with the bottom of the boat.

We had the boat out last weekend and the prop. seemed to be a decent match. The motor is at the lowest setting, but with the deeper style boat, the cav. plate looks to be in line with the bottom of it. At WOT with the motor trimmed all the way down I can hit about 5100rpm and by trimming up, I can get to the 5500-5600 range no problem. I didn't notice any excessive vibration at slower speeds. This set up should work for me.

Thanks for the input

it sounds like you've got it running pretty good... if it were me, and I had the option to change props yet (since it's a brand new rig) I'd try and get the RPM's up closer to 6000... I think you'd be able to do it with a 19... but that's me I guess... it all depends on what kind of load you were running when you got the mentioned RPM.. if it was with the boat full of people and gear you might be able to get 6000 by yourself and a light load of equipment... and if that's the case you're set...

Again... the recommendation is mine only... and my ususal mentalitly of tweaking things until they're running where they can be to get the best available performance.
