Can someone help me with propeller advice for a Goldfish 22 sport with mercruiser 4.3MPI 220hp. The boat has 24 degree v-bottom.

I know they delivered them with 14 3/8 x 21 ballistic back in the days. Some boats with same setup use mirage plus 21"

Any help?

Just to tell the truth , I HAD to google images of that

Whats the main difference between laser 2, mirage plus, yamaha M(proseries), Solas HR titan 3

The boat is 22 feet, 1200kgs. 220hp mercruiser 4.3. 46-47 knots with ballistic 14 3/8 x 21(in great shape) But my ballistic is damaged and I need to get a new one. Looking for better propeller

Ballistic and lasers they use to be designed for 2 stroke outboards.

In case of Lasers they work very well in light boats with not to much power. You can find good speeds.

Ballistics are best for V6 outboards. They got top end and fast response with all benefits of couped props.

But both are made for engines with high RPM ranges. (2 strokers outboards)

In your I/O case you will find best performance with Mirage Plus (couped) your engine push harder from low RPM, and runs longer gear relation than outboards.

Thus, there is some other options as Ballistic 4 blades who seems to perform good with I/O light boats.

With boats like yours, best is just to try. I would not be surprised if you find than a laser with long pitch will run better than a Mirage plus on range.

In light and not very big boats, everything is less predictable.

Ballistics Aquiles toe is they have very thin blades and its easy to crack them if the prop shouts out of the water.
