Anyone having issues losing engines? I've burned up 4 Yamaha 425's in less than a year due to saltwater getting in air intake in moderately rough seas.

Four? Thats wild, I can point you in the direction of some Yamaha guys but not sure they can help.

4 downed units would appear to be a hull manufacturing or design issue not a mechanical one.

What has regulator said?

I assume they want to keep you happy, that is their flagship.

Yamaha folks have been involved. They believe, as I do, that it is a Regulator issue. Regulator says mine is the only 41 with this problem, which is why I wanted to check around.

What order did they grenade in, port outer first? inners? have multiple failures in the same location?

I am really surprised to hear that Yamaha and Reg are not working it out with each other, YOU should not be involved or rather have to be involved. Regulator is yamaha OEM only correct?

I have a client who has one but it has the F350's. He has had a LU issue but no motors. I will call him this afternoon and get his opinion.

I have noticed on some of the larger CC's that when getting on plane, the amount of water up around the cowls can get worrisome. I have never noticed it on my boat but your reg is a bigger and heavier boat all around.

Out of curiosity has Yamaha covered the failures?

Trierarch

Four blown engine? Sounds like an issue with Regulator and not Yamaha.

Wow, a costly loss...hope it's covered by Yamaha under a warranty.

LTW

Yamaha covered first two(outer), then got suspicious and has made Regulator pay since for another outer and one inner. In anything beyond 2's, they take pretty steady saltwater in the air intake.

Any videos of the boat running in rough seas?

Rollo Tomassi

What are you going to do OP? Not use the boat unless it's flat calm?

SeaTreker

is there adjustment in the mounting height? if so, are they located properly?

LTW

Yes and sent to both Regulator and Yamaha

bahama41fl

Well that is surprising. Those are some expensive band aids Reg is using.

Have they advised you further replacement of future broken engines? Are they willing to just keep swapping motors like that.

What would be your ideal outcome if everyone was to come to the 'table'? New boat or a repaired and fully functioning hull?

Honestly I would look into an arrangement to purchase a new hull. It will not be free but might make the most sense financially for all involved.

This being said i assume this is a one off issue on this hull and not something that Reg has had repeated failures with. How could they if the repair is likely 50k a pop?

If you still have confidence with the brand and like the performance of the hull see if they will work with you. At this price point I think some concessions would be made without too much pain from either Reg or your dealer.

Not the first I have read about this issue with the 425s on the 41.

Saw this on another thread. Water did not look too bad, but it was not on plane so take it with a grain of salt.

Cobia 217

How about sharing where you read it with the OP? That's the info he's looking for.

bahama41fl

I can see water getting around the motors in this vid from 45 - 2:00.

Is this what you are experiencing?

At the 1:12 mark it appears that the outer motor is getting pounded with spray off the hull. I could see where that could flood a motor for sure.

Agreed. Holy crap, it is amazing how much water is being thrown off the hull into the bracket, and then up into the cowl of the Yami's. Big Regulator fan, but I'm not sure that is Yamaha's problem at all.

Rollo Tomassi

From that video it doesn't appear that the 41 hull and those 425's are getting along very well. That's a lot of water being literally dumped on those motors. Not sure how Reg fixes this.

Between the boat, the bracket and those bulky 425s it doesn’t look like a good match. I’m no marine architect but there’s a ton of water spray being thrown up on the motors in that video. The fact they are on the bracket isn’t helping. They stick a good 3 feet behind the transom getting the brunt of that turning spray. Any motor ingesting spray like that is going to prematurely fail. Even if the others make it longer than yours they will have a shortened life. Hope something gets sorted for you. Would be a shame if it’s a bad design. Maybe something can be made on the bracket to deflect spray away from the motors. Good luck
