8.1 Mercruiser
Here is direct from ACME
We’re coming out with 18x23 4-Blades with light/mod. cup when we have it plugged in at 4450 RPMs. We have this exact boat in our test data and these props they even gained some speed which it looks like you’ve got excellent speed now but it’s possible you could even get a little more. If you wanted the boat propped closer to 4600 RPMs we’d go with something closer to 18x21 4-Blades with mod./heavy cup. Based on the sizing and our testing data, we’d recommend part #1055-18.00X23.00C LEFT-HAND 4BLADE 1.50 BORE .075 CUP & #1054--18.00X23.00C RIGHT-HAND 4BLADE 1.50 BORE .045 CUP. We’d have to modify the cup to .045 Cup on #1054 right-handed propeller. We unfortunately don’t have these on the shelf right now so they need to be built. Lead times are running about 8-weeks. If you’d like the boat propped closer to 4600 RPMs, let me know, and we can look at something different in terms of propeller part numbers/size.
Just brought a 05 340 with 8.1... Had the boat pulled & pressure washed so clean bottom 1/2 tank of fuel on Survey with 4 people...
