Tight lines all!

Thread started about V6 Hondas and how to prop them.....refer page 1

Just adding my thoughts to that topic

Tight lines!!!

There is no over thinking there

As have always said, get height right then sort the slip then the pitch.

You noticed as the load reduces, Slip starts to correct, then once that sorted adjusted rpms with pitch last.

And it is very rare that someone actually can regonise these things by water testing.

They like to rev freely and when they do will deliver outstanding fuel economy from idle to trolling to cruise RPMs. Note these comments refer to gen 1 motors with higher gearcase ratio than gen 2 V6 Hondas.

My boat 6.7m Glasscraft Statesman with 0.7m fibreglass pod sealed and bouyant. Heavy as f**k as it started out V8/sternleg. Rated 300hp OB / 400hp IB.

Brought 2nd hand 225 Honda less prop, so tried the following props -

15 1/4 x 16 3 blade Powertech 5100rpm WOT no good

15 1/4 x 15 4 blade Powertech 5200rpm WOT no good

Both brand new with Honda sales rep on board, we both disappointed and bemused with results

Next i try a mint Suzuki SS 14 1/4 x 16 3 blade, good but to much WOT 6000+rpm

So i went with Solas [Honda] 14 1/4 x 17 3 blade, standard Honda dealership fitted prop for the gen 1 225

Performance and economy were good WOT 5800rpm, but boat feels like a old Holden station wagon to drive

Then i acquired a mint Mercury Rev4 14 5/8 x 15 4 blade. Performance is excellent, slightly higher fuel consumption but ideally would drop motor a bolt hole or 2 for this prop, but boat feels like a rocket ship on rails, flies out of the hole, and stays hooked up in even the worst seas. My go to prop for bar crossings. WOT 5900rpm

Next i acquired an excellent Mercury Enertia 15 x 15 3 blade. WOW, what a prop! Game fish trolling 8L/h

at 7-8knots heavily loaded with fuel. Cruising 24-26 knots 30L/hr. WOT 5800rpm, boat feels like a sportscar to drive. Awesome out of the hole and stays hooked up almost as good as the Rev4

So i sold the Solas and kept the Rev4 and Enertia

Conclusion - Buy a new or used 225 or 250hp Honda, bite the bullet and pay for an Enertia prop pitched to suit your hull [not the Enertia ECO, its a bigger diameter prop designed for twin/triple/quad outboards] and you will be a happy boatie

And Steps, please don't start overthinking this, you may give yourself a brain anurisim

I have done extensive on water testing and recorded data, but don't wish to bore everyone to tears
