Adding a 3rd log with transom

I'm looking to add a center toon with a transom. My boat is a 22' Bennington 2275 lx with 25" logs. The center toon will be 23' and 25" with lifting strakes. I have a few questions.
Should lifting strakes be added to the outer toons?
How can the max capacities plate be changed for a larger engine and weight? My insurance man (State Farm) told me if I go over the max h.p. And had a claim they could deny it.
How much lower do I set the center toon than the outside ones?

Thanks,
Tim

Most manufacturers only drop the center toon 1", Manitou's outer toons are 2" smaller though. I don't know if i'd ad strakes unless I was 100% confident in the person doing it. I believe you had to go through the Cost Guard in the past for new weight restrictions, but lately I've heard of manufacturers giving out new stickers to some people who've done it right, It's hard for me to believe it but I've heard it from at least 3 people in the last year. I would contact Bennington, they'll probably refer you to Cost Guard I would imagine.

If the center toon has lifting strakes, they'll probably get your nosecone out of the water. In that case, I wouldn't add lifting strakes as welding on relatively thin metal might cause leaking problems.

Sounds as if you need to get specific marine insurance elsewhere. State Farm's not pushing boat insurance, and I found them to be not competitive in either terms or rates.

When you add the third toon, just remove the plate. You're well within the 150 hp or more rating that boat would have.

The dealer added the third toon to my 24' Tahoe.
The manufacturer (Tahoe) just sent me a new data plate for the boat with a third toon.
I believe it took it from 150 HP max to 200 HP max.

I had State Farm boat insurance for over 15 years, and dumped them for Progressive about five years ago, when they wanted to double my premiums when I'd never filed the first claim.

I got much better coverage for less $$.

I have AmFam for my ...everything.

Here's the big kicker though:

When I gave them a copy of my BoatUS Boating Safety Course Certificate, they shaved $275 off the cost.

I want to add a center toon to my 20' pontoon. I will do the installation. I'm looking for a used or scratch and dent 25" diameter about 20' center toon plus built in transom and strakes? Close to Colorado as possible? Know of any?
I haven't found a way to get a updated hp capacity, and was told by multiple manufactures they do not recommend it and would not do it or supply a capacity plate/sticker. Most manufactures say they won't replace a original plate or sticker and to contact USCG or the state. The USCG and state say contact the manufacture.
I don't want a lot of hp or speed but the current capacity is 80 hp. I was thinking 150 hp would be more than I need but want enough to over come the extra weight and center toon.
How/Where do You get an updated capacity plate/sticker?
Thanks, Any recommendations or information would be great?

Unless boat insurance is crazy expensive in your area, or your overinsured by a LOT, I think you're paying way too much for your insurance. My boat is a 2017 Tritoon (23') with a Yamaha 150. It's insured for $40k absolute value. I only pay $235 a year. Sounds like you're paying a lot more than that, or at least you were before they dropped your cost by $275.
