Question Dealer limiting HP

So I have a 2000 30 proline it has the yellow placard that says yacht certificate. Boat is 32.6 ft and 10í10" wide and dry weight 8000lbs. I have twin 225ís and was looking to upgrade to twin 300ís. The boat currently does 34 mph with the twin 225 and when I blew one engine 6 miles out and was doing a top speed 4mph. I donít need to go 60mph I just want to be able to limp back at more than 4mph. If I have a engine failure again. So now I go to local Suzuki dealer and they tell me they will not put 300ís because they have a flyer from the boat from 2000. In the pamphlet it says max hp 500. So how do I get a letter from manufacturer saying it can take 600 hp? Also when boat it yacht certified I thought there is no legal HP rating. Anyone have info on this ?

The company has changed hands at least once since that boat was built in 2000. I doubt anybody would want to certify that the structure would hold up to the additional weight and horsepower if they didn't design or build the boat. I wouldn't. You are correct in your view that the horsepower is not regulated by any laws. It's a liability issue.

I'd tell them if they want your business they'll do it, otherwise you'll take it somewhere else. And take it somewhere else if necessary. There is no law that I'm aware of that says you cant put a big motor on your boat. It's your boat. By Gawd ain't this still 'Merica?

Print and sign some sort of "hold harmless" document? Works for whitewater rafting/parachuting/marriage right?

Put a pair o DF 250 APs on it and call it good. Exact same motor bolt for bolt except for the ECM that will limit it on the top end. Same hp and torque through all but the very top end of the rpm scale so you will not even notice a difference except in top end speed. Time to plane and cruise will be same as the 300.

They have a pamphlet? Like a sales brochure? How do they know your boat wasn't upgraded to get the "yacht certificate"? IMO it sounds like you need to go somewhere else. Put 350s on it just to show them.

Twin G2 HO 250's will run very close in performance to 300's.

ďNo offenseĒ but you just had to post that. Makes perfect sense.

Have you been on any of the new G2's? I own one. Yes they had some growing pains in the first few years.

I would own an brand. I'm not a homer of any brand.

But there isn't a 150 4 stroke Merc, Zuke, Yamaha or Honda that will touch it out the hole and low end torque.

There isn't any 4 stroke that gets the same or better MPGs as you go over 4,000 rpms. My MPG's stay the same or get better the faster I go over 4,000 rpms.

I know the 3.4 G2's are a different motor.

But my 150 G2' is much more fun to drive than any 4 stroke 150.

I owned a 150 HO and the hole shot was jet ski like. The refinement/smoothness was awful. I have driven a 300 g2 bay boat, power steering is nice the digital controls are cheap in my opinion. I have been on a twin engine 300 g2, and plan on going on a triple g2 300 boat. They have there positive and negatives. My over all experience with Evinrude is simply no thank you. I will take a mercury every day, then Yamaha or Suzuki.

I'd be concerned about why a single 225 couldn't push that boat over 4mph. That just doesn't sound right to me.

My digital control is nicer than the Yamaha 300 I had.

Built in rpms increase and decrease built on top of the throttle. Didn't have that on the Yamaha 300.

I set the throttle where I wanted and it stayed at the same rpms. Same as the Yamaha FBW 300.

This is getting more common than you might think. The other day I went to get new tires on my truck, the ones on it were 265/70R17 from the factory and I had the window sticker in the glove box that showed that but when I went in and bought 4 tires the dealer told me they could not install them because the placard on the door said 225/70R17. I got a refund and went to Walmart, I got the same speech from them, thankfully I got the manager to look at the window sticker and go on line to Dodge web site to see what they said and finally he agreed to install the tires but it took 2.5 hrs for them to work that out and he suggested that I go to Dodge and have them change the placard because no tire dealer would have done this.

It's 'Mercia" all right.
If that was my business, I'd tell you take somewhere else.
Because the second the yard puts on those engines, or even sells them to him and them know that the boat is not rated for it? They are liable.
And being 'Merica", THT and all, next step is pitchforks, barn buring and getting sued.
Fact of "Mercia".

Land of litigation. I'd be reluctant to do it if I was a dealer in the US too.
