[Moderator's note: the way this poster has posed his question requires that only owners of a MONTAUK 17 with a Yamaha VMAX 90 SHO engine should reply to this inquiry.]

Q1: what propeller are you using on the Yamaha VMAX 90 SHO engine on your c.1994 MONTAUK 17?

ASIDE: I have ordered a Yamaha VMAX 90 SHO for my 1994 MONTAUK 17.

As a result of owners testing their Montauk 17 with the Yamaha VMax 90 SHO, the recommended propellers include:

13 x 21 Yamaha Painted Stainless Steel
13.25 X 20 Mercury LASER II

Size applies to the specific brand/model only and is not transferable.

The engine should be mounted two-holes-up with the top engine bolts in the third-hole-down from the top of the engine mounting bracket.

Q2: do you have any performance data for the boat with its previous engine?
