Do i need 25P prop on 225 optimax xs

I have 21 ft triton with 225 mercury.
Someone put a 27 p tempest, i was told thats too much prop.
So I'm looking for advice or used (or trade) 25 p prop ( 4 blade)?

Thanks for the help in advance.

Need need know how many RPM's your turning now at WOT trimmed out and how is your hole shot.

The tach is not working but hole shot seems week and also , seems weak when trying to go those extra 6 inches on the trailer.
WHen I had the engine checked the computer said it has about 10 hours since a rebuild and RPMS were never over 4900 so that was another clue prop is not right.

I 'm looking for someone to fix tach in DFW area if anyone has any recs.

Thanks

I run a 25p Trophy on my 99 TX21/225 Opti most of the year. I drop to a 24p Trophy in the hot months of July and August. Keeps me right at 5700 rpm WOT

You can buy a new tach for not a whole lot of money, most likely a 25” would work better for you; but you really need a working tach.

I have a 25 and a 24 pitch tempest prop that I am selling

Also, check prop to pad height. Start at about 3.5" below pad and fine tune from there. I went from a 27 three blade to a 25 4 blade on my Champion 201, set the prop 3.5" and the hole short improved dramatically. Top end dropped 4-5 MPH. Still runs about 65 +/- with boat loaded and two guys on board.

27 sounds a little steep, but it's hard to say without knowing what RPMs you're turning... Get the tach fixed and borrow a known 25 and give it a try... Might also try calling around to a few long time Triton dealers and ask for advise... Dan
