what issue is that?

496 mag ho, bravo X, 1.65 gears, 30P Bravo 4 Blade. 72MPH on a good day @5100RPM. Cool dry, low fuel, light chop, and one person.

Now my next question for 27 owners is what trim and tab setting are you using most often. I'm still getting used to this thing and it feels like it wants more drive trim up but it seems to porpoise without any tabs which to me defeats the purpose. Like I said first fountain and still experimenting with settings. Just never really had to use the tabs etc with the formulas and scarabs I'm used to.

Cruising: Drive 3.5-4, tabs 2.5-3

Cool deal that's kinda what I was feeling in the boat as well yesterday.

Not sure how many owners our 27 had prior to us, but it had a RH 22 Bravo I on it when we got it. I later replaced with a 24p Bravo I, and the boat really liked it. (502 Mag MPI).

Since you are new to Fountain, and assuming performance / stepped boats, you should watch the Reggie how-to video on youtube. If nothing else, listening to his accent is worth the time!

not new to performance boats at all just fountains. I spent tons of hours testing the hawk on some formulas for merc and the fountain feels way different even by those standards lol. drove a few talons, scarabs, baja etc for them as well and its just a different feel. I just like to do a little research and ask a few questions and learn a little before I put me and or my boat/any passengers in a bad situation is all. saw the video as well a long time ago and yes its worth a watch even for the accent lol.

3 on tabs is neutral 3.5-3.75 neutral on drive
cruising in rough water 3.5-4 on tabs 3.5-3.75 on drive
cruising on smooth water 3 on tabs 4 on drive
WOT speed run start out at 3 on tabs trim drive to 4.25-4.5 as speed builds then lift tabs till you feel the nose rise and get light 2.5 or so depending on water conditions the boat will let you know if you need to lower tabs back to 3

I know not a Fountain but for what its worth my first boat, a 21' Evinrude Rogue boat (no misprint) had a V-6 engine with OMC outdrive Left Hand prop.

To all reading, I have a left hand mercury factory labed 28 4 blade
If anyone needs

I lost a right hand prop years ago one day & have always had this left one sitting around .....always Figured it would be good for guys with single fountains
Seeing this tread reminded me..... Pm if more interest.
