Welcome fellow Canuck

How far out can you trim the Aluminum prop before it starts to vent?
Is there a Merc dealer near you that has the demo prop program? that way you would be able to test before you choose the pitch/ I never compared my Enertia to the original Aluminum, but it is 1" less pitch than the original prop. Great prop for elevated engines, but still works pretty good submerged. I changed the vent plugs from the factory solids to the medium sized holes.

What is the max rpm for your engine 5000 or 5200?

I originally pulled the 21 Aluminum off and ran a 20 Raker, gained 200 rpm and 3 mph. Tried a 22 Raker and lost 400 rpm, gained 1/2 mph over 20 Raker. Switched to 20 in Enertia lost 75 rpm compared to 20 Raker gained 2 mph.
If I were you I would try a 21.

Your results may vary
