Anyone recommend somebody in Vic to help me choose the right prop for my boat. I’m running a Yamaha 115 on a Malibu 182. Does about 25mph at 4300rpm. When it’s a full boat it has a hard time getting up on step
You may have too much pitch. Will it run up close to 6000 rpm at WOT? Check with the experts but I have a F115 on a Malibu Tyee. The prop has a 15 pitch and the boat jumpsAnyone recommend somebody in Vic to help me choose the right prop for my boat. I’m running a Yamaha 115 on a Malibu 182. Does about 25mph at 4300rpm.

Do you have a HydraFoil on it or just stock? I had the same boat with a 115 Honda that is heavier than the Yamaha. I put an SE200 Foil on it and it made a huge difference with lift and was cheap. I know there are a lot of Foil haters out there but I had them on my last 2 boats and for those set ups worked well. You can go with 4 blade props to get some lift but with a 115 it might be a bit shy on power. I also kept a few spare cannon balls up front in the anchor locker along with a fair bit of chain...anchor and rode for a safety anchor. (Not a full Hali set up)
Hopefully the winds are down this weekend and I can try to get my wife open throttle reading while on my way to a Ling spot
good call, the prop experts will want that info

Also make sure that the motor is high enough on the transom. When you are on plane the anti ventilation plate should be skimming the surface of the water. When I got my boat the motor was mounted a couple inches too low and performance was terrible. After I raised the motor to the bottom hole on the bracket it was like a different boat.
Mind me asking which hull you have. I've considered raising mine but have found the Double Eagle style hull can be sensitive to ventilation when the motor is run much higher than a near level vent plate height with the props I've tested(mine is 1/8"higher).
Some hulls perform much better with the plate higher than level. Props with more cup and rake or 4 blade can be less susceptible although as with tires most props are a trade off.
Once you're on a plane how far up can you trim the motor before the prop loses traction or vents?
PS I'd put thermostat near the top of things to check while doing preventative maintenance.
