Hello everybody. I apologize for asking a question that probably have been asked several times, but I need a quick answer.
I am repowering my Montauk 190 2011 with a brand new Mercury 150 Fourstroke.
The dealer is asking me what kind of size of the propeller I prefer...
I have no answer apart that I have been told that Enertia 17 pitch is the standard choice.
Let me say that I do not need great speed as a Montauk 190 with a 150Hp engine is already at the upper limit.
I mainly use the boat to fish at low speeds and from time to time I cruise at 15-20 knots (maximum), only occasionally I try to go faster, but this is the exception.
I prioritize also cosumption and, really, I need only a standard propeller, not a special one.
This said...any advice?
Thank you so much.

Jack -

If you look at Mercury Marine's site, you will see the recently re-designed Mercury 150 FourStroke has a gear ratio of 1.92:1 and a WOT of 5800 rpm.

Boston Whaler posted performance reports for the 190 Montauk. Their test of the Mercury 150 Fourstroke back in 2011 has the same gear ratio.

They sell the boat/motor with a 14.50 x17 Enertia prop. This is a non-special prop.

Make sure they mount the motor at least 2 holes up, if not 3.
