This is probably a question you haven’t heard before. I’ve been running trials on a new boat that I’m finishing up for a client and it’s too fast for safety. OK with an experienced, careful and sober operator, but not something I would turn a couple of teenagers loose with and tell them to have a good time. They would hurt themselves with this rig and I don’t want anybody getting hurt with my boats.
The engine is a F90 Yamaha, installed by Charleston Marine, and it is sweet:sunglasses: My question is, is there any way to install some kind of governor, or RPM limiter, or throttle stop, for when the kids use the boat? Something that could be easily turned off or on, but not too easily.
Appreciate any thoughts.

Jet skis have learning keys which limit RPMs to a safer level, I see no reason why today’s modern computerized outboards couldn’t have something similar
But, there is a convenient pigtail looking device known as a kill switch,most modern day engines have them,they work well.

PS, I build custom boats for a living and am well aware of a kill switch function. Thanks though for pointing that out.
And I assure you that if somebody gets hurt in one of my boats, it is my problem. If I recognize a potential problem and don’t take due diligence to resolve it, it could be my problem in a courtroom, as well as a moral issue. I like sleeping good at night myself.

Is there a throttle stop on the linkage under the cowl or in the binnacle? Larry I’d look good at the linkage and maybe there’s a way to adjust it so it won’t go WOT.
Cracker, unless you put the mildest prop you can get on it, you can try to find a cheap computer diagnostic tool, so the owner can change the motor settings. If the owner is willing to find a happy medium on the maximum speed any shop should be able to set it up so it doesn’t go over a set point. If the owner isn’t willing, I’d put it in writing on the sales contract that he was warned!

I don’t know, that’s why I’m asking a Yamaha expert

Too late for that. My client was with me during speed trials and knows better. He wants all the power available when he uses it, but wants to limit it when his kids or others use it. I told him I would research it and find a solution. That makes it my problem.
The prop is about perfect now, turning 5900 rpms at WOT. I hate to over prop it to slow it down and load up the engine. Swapping props for different operators would be a pain too. There has got to be a simple way to do this.

Yall want to see her run? This is from a dead stop to half throttle. Not enough room in this creek to open her up. There were a couple people fishing in a jon boat just past where I stopped, didn’t want to ruin their day either.
After seeing how beautiful your boats are, I could think of a dozen reasons to not let the kids use it by themselves, and speed ain’t one of them. I wouldn’t want my kids operating a boat as nice as yours with a trolling motor.
Thanks for that, but it’s as tough as it is pretty. If you notice at the end of the video, I ran it right through a tree at about 35 mph. with the owner filming:smiley: I turned the wheel but the boat didn’t turn. Went right through some trees sideways. Didn’t put a scratch on it.
At speeds over 30 it handles just like an air boat, you turn the wheel, the bow turns, but the boat keeps moving in the original direction. And it hits 30 at less than half throttle. It takes a half mile to turn it around at 40.

On the handling, I notice a lot wooden Bateaus are built with the 2 runners/strakes like you have, as opposed to the deeper triple strakes running the full length of the boat on a Jones Brothers. What is the reason for not wanting to have as many strakes as possible for tracking?
quote:excuse me Georgia Cracker, you asked a "crazy question".
I didn’t know my question would draw out the crazies, so I edited it to unusual.
quote:
Chris V and Charleston Marine should be the one concerned,they actually bolted the motor to the boat,correct?
Absolutely not, I don’t pass the buck. It’s on me. This boat is a one of a kind, there is not another one like it in the world. It doesn’t come with CG stickers or max HP ratings. CM installed the engine that we ordered and did a beautiful job of it. I’m hoping they can answer my question, but they have no liability in the matter at all. The buck stops here.
If you don’t have any useful input, go poke your salad or something.

Just consider the source… Awesome looking boat BTW!!

Very good question, it deserves a good answer. I’ll try. Got to build a drink first

See if you can get a call in to Mr.Chris or to Yamaha,maybe someone would be able to answer that question.
Maybe you could suggest that to the motor builders for future safety isses.
Double D.
Dang, apparently some people just can’t help being a fool. The boat turned out beautifully Larry. It is really neat to see it finished since I was able to see it in it’s earlier stages. I know its tough but I’m not sure I’d turn kids loose in it alone.
