I have a 260 DA 350MPI and I'm considering changing my props to a new set of 4x3 's. Has anyone with a similar boat tried this and is it worth the money to make the change? :smt100:smt017
Have you seen a difference in cruising RPM. Do you stay on plane at a lower RPM. I'm thinking of going with a 4x3 set but not sure if it's worth the money.
i'm trying to improve over all performance not looking for more top end just more efficiency. Would like to stay on plan at say 3500 rpm instaed of 4000
The reason being with the new configurations of 3 and 4 blade combinations . Volvo uses a large 3 blade and smaller 4 blade .I don't know if this configuration would work with merc although if it does with Volvo way not.
My neighbor was the previous owner the drive was never changed .I can not find the number right now but believe the ratio is 1:50. The boat probably has a gross weight of 8K lbs. figure on average 65 gal fuel ,20 gal water 5k kohler gen. My othert boat did have 2's on it
Thanks , The reason I'm asking is , my last boat was a 31ft go fast, big blocks and Bravo 2's. I changed out my 3 blade Mirage props for 4 bladed props and realized a significant improvement in cruising range.
