Hi Guys, after some advice setting up a tunnel. Have a few 3.5cc's (OS outboards and Prather lapcats) that I have built and have been for recreational use, would like to get some pointers on getting a bit more speed.
Current prather lap cat hull and OS 21xm. Standard plastic prop. 10% nitro. Seems to run happily at 50kph on the GPS.
I see there are guys getting upwards on 50mph on the standard OS outboards
Other props I have
Prather 215
Prather 220
Octura X442
Octua X440/3
After some advice to get a good gain here. I am assuming one of the above (the 215 is a popular prop?) or any other recommendations, maybe professionally balanced etc? I mix my fuel so can increase the nitro %. Is there any other pointers or things I can change to get the most out of the boat setup?
