Great feed back on the issue guys. I will run it with the tech on Saturday morning. My main concern is that the motors run WOT at an RPM that makes them happy. If I had wanted a 55 mph speed merchant I would have kept my Mako 284. The wife kinda likes the A/C, V-berth and such in the 32.
Like a lotta guys, WOT is not a normal throttle setting for me. But, we will have some initial diagnosis to share with y'all Saturday night. I have full faith and confidence in the boys at both factories.
Mike,
Winds are 10-20, was just on 50 and 19 getting gas, and folks were fueling up the boat...whatever, from the east, stack the waves up...good afternoon to drink beer, cut the grass, take a nap,...

Now it's you that's beginning to sound like Lanie.
Drink some beer.......
I'm guilty as well.
I'm at CASTAWAYS and at five sharp the COORS LIGHT lamp is lit.
Is that Castaways in Marathon? I'm guessing no test results or progress due to the wind blowing in the keys all week- just fished 4 beach chairs out of the pool yesterday.....
That is all you are going to get out of this boat with 225's. I rode a older 30 with 2S EFI's, did about the same.
Maybe, but maybe also just a little more.
It's an RPM issue more than a top end issue.
There's also a lot more to it.
Right now it's got me stumped as to the solution.
Lots of conversation today internally, and the marina, a very good one, that ran the boat with the customer.
It's 2 1/2 years later.
I dont have an answer.
It's not a boat issue, it's a motor issue.
Maybe, a prop issue, but I disagree.
Everyone always wants to run to the prop pitch.
The fact that we delivered about a hundred of them without the issue, same props, gives me to believe changing the prop pitch is not the answer.
It's not a drastic underreving issue.
Losing some RPM's, different circumstances, not very uncommon.
This is not some mortal sin situation.
But, I like the customer, he wants an answer, and I'm not 100% sure we can satisfy him as to that.
But, I'm trying.

No, CASTAWAYS in Melbourne.
Wind was blowing pretty bad there also.
Yeah, I know.
13,500 pounds heavy
Whatever light?
Clean bottom?
Bottom paint?
Conditions?
Trim?
How many variables might get thrown into the question?
Fact is, the customer is a good, and straightforward man.
He has an issue.
It's 2 1/2 years after delivery.
I do not doubt, for a moment, the customers honesty and sincerety as to the matter.
Every answer carries with it a counter answer and liability that we must consider, while trying to satisfy the customer.
If it were my boat, it wouldn't give me much of a bother.
Sure, lets get the RPM'S up, pick up what, three, four MPH at WOT?
It's not going to get to thirty eight or so because of the bottom paint.
That's not happening.
It's all an issue to Dale, thus we pay attention.
I'm trying a few differnt avenues, dont know if I can find that silver bullett for him though.
I will try.
He's a good guy.
So, 1 week later, have any "silver bullets" been found, prop wise? And what about max trim to the point of ventilating?
No, a "Silver Bullet" has not been found.
The dealer that sold him the boat about two and a half years ago, has delivered perhaps a hundred or so of the model with the same props with no similar incident that we're aware of.
Of course changing the pitch will change the RPM'S. The boat right now will change RPM'S in different coditions. I believe the customer has told me that there was about a six hundred RPM change as to running with, as opposed, to the wind.
The RPM'S will vary as to load, bottom paint, and other changes of conditions.
So, change the pitch, increase the RPM'S in some conditions, and in other conditions, then over rev the motors.
We did look to see if we had some "test props" we would loan to the customer to try. We had none of the correct size that would be needed. My boss was not crazy about the idea, but went a long with it. If we supplied props that would over rev in some conditions, blow a motor, then who carries that liability?
Sure, it's a problem that I have no answer for actually more like two weeks later.
If many other boats with 225's were delivered and ran in the high 30's or low 40's with 17" props why would anyone on this board suggest a lower pitch?
There are 3 possibilities in my mind.
Props are labled 17" but are not.
Fuel constriction.
You could throw in motor problem like low compression or dropped cylinder however it would be more likely that one motor turned up to 5300 or so and the bad motor 4800.
A very, very remote possibilty is the motors have the 200 computer, not the 225 or the vtec is not kicking in.

Some of the issues you bring up goe's to the beer bet I had with one of the guys in our engineering dept.
I still dont know answers to all of it.

Just wandering if they figured it out????? Did this dealer rig 100 32' proline express's with twin 225 honda's???? Now one out of a 100 wanted bigger or different engines?
I go back to the honda's 1.86 gear ratio and a 17p prop needing to run at least 40 to get the propper RPM per the mfg rpm spec. What happens when it full of fuel, gear and people??? RPM and speed going to suffer more.
