Hey crew,
Just in the process of repowering my 2007 Seapro 238WA with a new V8 300hp Verado and looking for anyone who has the same set up and any suggestions on Prop size.
Had a 225hp 08 Verado and all sorts of fun gettin that one proved right so hoping someone in the Seapro community can help save me some time.

Cheers Phil, guessing this is for the 6cyl Verado but great starting point. Would be happy to get these results.

Be close I rekon although the V8 has a 1.75:1 gear ratio so might be a little faster or you might need to increase pitch if you exceed max rpm.
A good starting point though.

Didn't know they were making an 8 cylinder Verado. What's the advantages?

Hi crazydave,
I have just brought a Seapro 238WA and having some similar issues to one of your previous threads, about 5500max rpm. Thinking of going from Mirage Plus 17p to a 15p??? Only getting about 33knots flat stick. Motor is mounted on the second hole up from the bottom.
What was your best overall performance in the end with your 225? Prop, speed, fuel usage etc. I have the same 225 Verado. Any advice appreciated mate!
