What Did You Do To Your Boat This Week?

[Aquaholic]

Well the verdict is in, ran thru a little over a full tank of gas (350L) got a pretty good idea how it performs.

-2.7mpg average, was 2.4mpg (12% better)
-Hole shot just a bit worse but still ample
-dropped a good 400RPM at any given cruising speed, 30 knots at 3800 (was 4200rpm)
-doesn’t rev up to full RPM’s as expected but top speed still improved slightly. 44 knots at 5300RPM. (Was 42.5 knots at 5900)

Enertia ECO 16x19P vs Enertia 14.5x19P

Overall I’m happy with it.

If they only made a propeller with a 1 inch pitch difference, you’d be right in the middle. Better hole shot, and be in the power range a bit more but still better mileage.

I agree, and they actually do make an Eco 16x18P and that was my instinct but dealer recommended all along was the Eco 19P
The prop game is an expensive one to play tho.

What is the boat and motor?
Just curious...that seems like good mileage and fast.

Good numbers. I'd suspect the 18P ECO would be even better...and get those revs back up at WOT.

I run an ECO on our Yamaha 250. Lost a touch of top speed (2knts slower - 41 to 39) but efficiency improved, as did low-speed maneuvering. The whole boat rides higher at speed and flatter.

Looking for some advice

18' boat has this extended pod.
2022 yamaha 9.9 mounted on that welded aluminum bracket bit.
It drags in the water (prop) when fully trimmed up and the transom mount piece that projects down. I want to raise it up so it sits out of the water while trimmed up.
Can I remove it, drill new holes higher up (probably 2" would do the trick)? Does it need to be perched resting on the top of that bracket - I assume thats ideal.
I'd rather not use one of those pivoting kicker brackets as I use a bar to connect it to the main for steering while trolling on it.
Appreciate any help/advice.
Cheers

Your kicker bracket was measured/designed for a motor without power tilt. The power tilt units have a much longer bracket.

Best advice would be to have a welder extend the bracket upward so that you can get all four mounting bolts attached (ditch the hand tightened clamp bolts and just use mounting nuts/bolts). This will lift your kicker a bit higher, so I would only do this if the leg is long enough. Otherwise, you should extend the mounting plate downward (which may drag in the water at low speed, but should be fine when planing)

It definitely doesn't need to be perched resting on the bracket, most mains aren't. As mentioned extending the bracket and 4 bolts are best but you could try drilling higher on the bracket to see how it works.

The flipped air cleaner cover gave many a smile back then.

Recently I watched a dyno vid with flipped air cleaner vs. Not and it made 8hp more flipped lol

I could’ve had a lot of eight dollar payoffs back in the day when the know it all’s said it just sounded like it was making more power.
