Default Prop Advice

I have a 2007 Lund Classic 1660 console steer with a Merc 60 HP 4-stroke. Bought it this year. It has a 10 pitch prop on it. Works OK on the front range (slow to plane, but will get up to max RPM at WOT), but it's a dog in the hills. Tried it at Spinney with my dad and niece, and without having dad get in the bow it would only turn 4000 RPM.

I know I need to go down in prop, but not sure how much. Jim's Prop Shop says go all the way down to a 7 pitch. Prop Doctors say 8. I'm not that concerned about top end, but I want something that I can continue to troll with, will plane out without having to sit in the bow, and not cause me to over-rev the engine (does this engine have a rev limiter?)

Is there anyone with a similar set up that can offer what what they are running?

I have the same boat, but a side console. I sold my 60hp 4-stroke Yamaha on ebay. Installing the 90hp 2-stroke Yamaha wth my buddy was a beast, but thank God for my friend! No hoist I went with a 2 stroke because the weight stayed almost the same. The weight didn't void my Lund warranty but the 90hp sure did. Lund claims I overpowered it. There are a few boat test websites that have this boat going 39-45 near or at sea level. Lund doesn't care that I can't go over 37 on the front range or over 33 in the mountains (using 2 different pitch stainless props). Hopefully I won't need the warranty. You on the other hand can upgrade to a 75hp & not get your warranty taken away (the side console can't, but yours can). Call Lund to confirm before you do anything drastic. If you stick with the motor you have, you'll probably be frustrated until you change boats or move to sea level. I tried a few props on my 60hp before I made the switch. Plus, you have the added weight of a full windshield/console. PM me your # if you want to brainstorm a bit more.

This may be your best solution for the money....I ran one for years and the difference in performance was amazing. A lot cheaper than a new motor...although you may still need to change the prop to a different pitch.

You can read the reviews..

That's the brand I bought before switching to the 90hp. I tried a number of props & that. I left it on there with the 90hp because it still helps me plane out quicker. Sometimes it jerks the wheel/steering though. It's very dangerous to let go of the wheel if you have a hydrofoil- at least in my experience & with my father in law's boat too. Very dangerous!

Hmmm...Like I said. I ran one for years on a 17 foot Larson with a 140 horse inboard. Huge difference in the hole shot. Gets you right down on plane. Needed it to pull big skiers...Never really noticed the dangerous aspect ...but then again, never really let go of the wheel when running across the lake.

I'm with you. I never let go of the wheel, but because I feel a strong pull at times I do warn everyone who drives it. If they let go of the wheel we will be in the lake. My FIL was used to letting go of the wheel (not sure why), then he put the hydrofoil on there... first trip out him & my BIL almost went swimming at Spinney.

I have no desire to change the motor out. My other boat has 300 HP. When I have the urge to go fast I'll take that out.

The foil is an interesting thought. I had one on my last boat and it did help the hole shot. Might be worth considering.

I have a similiar set up as yours, it's a 2007 Tracker Targa 165 with a 4 stroke 60 hp Merc. I have to run a 10 pitch prop at Pueblo and a 8 pitch prop at Spinney. This setup is about a close to perfect as I can get with an underpowered motor....wish I would have went with the 75 hp but it gets the job done. Prop Doctor's are the ones that hooked me up with this setup, they seem to be good people. The 8 pitch will plane the boat out with 2 people (including driver) on board at Spinney or Twin Lakes but if you throw in a third you will need someone in the bow to plane it out. The foil sounds like a good idea, I might have to try that.

Just keep going down in pitch till you get the rpms to redline . Thats as fast as she'll go-

That is really, really dangerous! Don't you have the little tab on your motor (not sure what it's called) to trim to correct that?

I can let go the wheel rolling down the lake wide open with my Yamaha 200 and it runs as straight as can be on flat water.
