try some 28's labbed by Merc ....

I've got 28s, but they're not labbed, I think I need to turn some higher RPMs.

That's what the lab will do, gain the 3-400 that you need ... You could try the 26's but I'm afraid you will loose too much lower end ....m

Yea, I can't afford to do that, when the boats loaded it's hard enough to get her up, out and moving, as I'm sure you know the 353 is one heavy boat, just trying to max my speed with what she has since she's only turning 4,700-4,800 RPMs

When I went to the 353 from the 311 I was really concerned with the difference in planing time ... But after getting used to it....no big deal now .... It will pop right up ... And I'm turning 32's ....

What?

and there's no guarantee that labbed 28's won't slip more down low as in putting the boat on plane

for the cost of a lab job you can pick up a pair of 26's and go from there. If yur a happy guy peddle the 28's

quite frankly the 28's aren't working for you anywhere except at mid range cruise.

Speed .....low and mid .... Actually prob will plane better ...but as stated you have to try it .... They are ALL different ...m

I think it's probably the easiest and cheapest to try a set of 26s first, then go from there.
