Journeyman;
I read you have 350's on your '08 Marlin.
Good match? Is she stern-heavy with the engines and a generator?
The fuel burn is a bit better than the 300's with more speed on the Grady Site Performance Section.
Curious..
I think they are a fine match, If not a bit of overkill. When I was hunting for this boat, I would have bought her with 250's as speed is not high on my priorities. I'm happy with them though. The torque is unbelievable! She absolutely jumps out of the water!
Yes she sits a little low, and yes I have a generator. When I'm full of fuel, the bottom of the deck drains are just below the waterline and rear scuppers are about half under. I always burn the Aft tank first and after she drinks about 50 gallons, both are dry. With the 350's pushing me around, weight is of no concern.
Some numbers I posted earlier for my 350's. I believe they are close to what GW has posted.
3800 rpms, 31 mph, 1.3 mpg
5700 rpms, 49 mph, 0.8 mpg
Conditions - 1 foot chop, 250 gal of fuel, motors trimmed slightly, no tabs, 2 people, live well full of Macs, full gear.
Since then, I was able to get her up to 52 MPH one day last season. Lighter on fuel and no livewell. I didn't look at my numbers as I was holding on for dear life! Ha Ha! Never been a top end guy anyway. Conditions rarely allow for that.
I absolutely love this boat. It would be a sad day if Grady ever decides to take the Marlin out of production!
