Hi

Just wondering if anyone of you already got some experience?
What is the best prop to go with?
My boat (MCX with powerslot) came with OJ 13.7 x 15 four-blade.
At top end I do reach about 41mph with 4700rpm.
I think there should be a possibility to gain some hole shoot and have little higher rpm at the same speed.
Any recommendation with props ACME, OJ, etc.????

Any information highly appreciated!

Contact TT member EJ OJPROPS by pm or call 1-800-359-9730, tell him what you have, what you want to achieve, what you use the boat for and he will help you.

A 1281, 3 blade acme is the way to go. You will be impressed by this prop and the way your 197 will handle. You will gain more speed and rmp's.

I just bought a 2007 197 TT MCX and I am having the same problem, slow out of the hole and 41 MPH top end at 4200 RPM. My 1993 285 HP Nautique had a much better hole shot and 47-48 top end. I'm looking for both a quicker hole shot and more top end for barefooting. What prop do you recommend?

xpert you do need another prop. I have the same engine -- no powerslot -- and a heavier boat (X-9) and my boat is faster than that with good hole shot.

I changed my 89 Prostar PS from the factory 3 blade to the OJ four blade and loved it. When I bought my Maristar 200 I spent a few more bucks and got the OJ XMP 4 blade and couldn't be happier. The hole shot is quick and smooth and I lost no top end speed as some people said I might. The biggest difference is how quiet the prop is, no vibration noise no matter how hard I hit it pulling up a skier.

if you are looking for some better hole shot, you may want to consider this setup....

Yeah, on my 1004 PS 190 I just replaced my OJ 3 blade with a OJ 4 blade and found exactly the same, see my post on X star / prostar prop

Xpert,

For what it's worth, I have a 2003 TT 197 with the Predator engine (310 h.p. vs. your 350) & powerslot. I had a factory original 4-blade stainless 14 x 20 (omitting decimals for simplicity). WOT was 43 mph for me at 4350 RPMs. I wasn't happy w/ the RPMs being lower than Indmar recommended so Eric suggested I switch to an OJ 13.7 x 17.5 XMP. After doing so, my WOT RPMs are around 4650-4700 and max speed is still 43 mph.

I gained a little better hole shot, though I was hoping to gain 1-2 mph. I could do without the change in hole shot as I barefoot mostly and never hammer it anyway (at least not right away).

As far as I know, our hulls are still almost identical, and I can't imagine the 40 h.p. making much of a difference at all.

Hope this is helpful.

Dano or anyone else, do you have any specifics on the gains made by the 1281 3 blade?
MPH gain? What did it do to the table? is it still a good barefoot table with little turbulence?
