I’m currently in the process of upgrading my boat with a few modifications that have started off small & working my way all the way up to possibly a bigger engine if needed to get to where I want to be. Keep in mind I’m going to utilize almost every resource I can before spending the big dough on the new banger. This will include blueprinting the hull also if need be.

This is the rig:

Hull: Enforcer Super G
Engine: Zenoah G230RC w/clutch (23cc’s & 2.8hp @ 13k RPM)
Stock with can exhaust
Prop(s): P275 stock, P280 mod, & X470-3
Mix: 7oz of Pennzoil Synthetic to one Gal

Upgrades to be done: Two new props--- Mod P280, Octura X470-3. Also have a wet tuned exhaust to be added for the next series of tests.

The P280 was ran a few times to see how it did in stock form a few weeks ago. It lugged the engine pretty hard & never would wind out, so I cut the tongue area off, rounded the tips 3/16”, & added 1/8” rake or back cut. This is supposed to be good about helping the prop unload.

The X470-3, got the tongue cut off also, but no back cut. Besides that, both props received a good balance, sharpen & polishing.

Anyhow enough of the bs, I ran each prop at the same strut height (max’d out) & got these results per GPS…. Lol. Water conditions sucked as always because the boat stuck due to no ripples. Also notice I’m running without the trim tabs. Do any of you out there think that would help in top speed #’s ? I personally don’t so the reason for not using them. Maybe in the handling dept they would, but for straightaway testing I don’t think so.

The first photo posted you’ll see the lineup. L-R: New P275ss that hasn’t been touched, P280ss Mod, stock P275 beryllium copper, & last the X470-3 Mod before polishing. Also in there is the tuned pipe. (please ignore the plastic coupling, it will be fitted properly before use).

As always, I’m killing time & having fun doing it.
