Oversized Motor question

[Rooster_Smasher]

I have a 16' deep V that says it is rated for a 35 Hp. What will the issues be if I put a 40 Hp on it ???

Dont know what the dry weight of the 40 Hp. Is it a matter of dry weight or the amount Tourqe ??? Or Both.

Or is it a matter of just a ticket ??? LOL...

I have a line of a good 40 Hp at a good price.

Thanks,

Rooster

your biggest problem with going over the tag rating is insurance.
The tag is just a recomendation by the manufacture for legal issues.

What will happen? To the boat: not much. You might gain 1-3 mph. The difference in weight will be negligable as most 30-50 hp motors are built off the same block and use the same lowers no matter the brand. So weight isn't a big issue. You will get on plane faster for sure.

What will happen to YOU: If the sherrif, DNR, or Coasties find a motor on your boat that is over the rated HP you will get a nice (not free) tow back to the ramp, along with a nice fine and a ticket.

Not really. They get those numbers from testing, coast gaurd recommendations, and common sense.

They can and will issue tickets for overpowering a boat just like they will issue ticket for having more people/weight in the boat than is listed as it's capacity.

That's the first time I've ever heard of that!

I seriously doubt that a sherrif is going to check your rating tag and then write you a ticket and tow you back to the ramp for putting a 40 hp motor on a hull rated for 35.

I'll have to do some digging to find out four sure but we've had this discussion before and it seems to me that it's not illegal to exceed the recommended rating but not suggested either. I mean it's not like he wants to hang a sixty or a ninety on there. It's only over by 5hp.

I wouldn't do it. Stick with a 35.

Step one: hang your motor of choice
Step two: remove tag and eighty-six it.
Step three: tell anyone who asks (and I have $10.00 that says nobody ever will) "I dunno, this is how I bought it from the last owner".

since when? Worked at a dealership for 12 years and never heard of a ticket being issued. All we did was have customers sign a waiver when we would rig a 300hp on a bass boat. The truth to the matter after a boat hit 21 feet it does not need a rating.
This would be the same on a car how many s-10 do you see with 350 in them. no ticket issued unless you go over street legal horsepower.
You will not get a ticket for this. I can take a 35 hp and do work on it and make it into a 50hp and still put a 35 cowl on it.

[waterfoul]

Well, I have seen a ticket issued for too much hp on a boat, a smaller fishing boat rated for 40 hp that had a 75 on it... so there you go. I've also seen tickets issued for having too many people onboard. Go over the weight on the tag, get a ticket. If you're boat doesn't have a rating... there must be a place for every passenger to SIT on the boat... be that in the cabin or in the cockpit. The floor does not count.

Boat manufacturers seek Coast Gaurd approval before bringing a boat to market. Try selling boats the Coast Gaurd does't approve of in the United States.... I'll bet you can't. Then there's the AYBC standards.

It's not at all about the insurance ratings. It's about safety.

I also agree that going over by 5 hp won't be a big deal to anyone involved. BUT, they can issue citations.

Is powering above the rated maximum legal?
The United States Coast Guard has an opinion on this frequently asked question, and their answer from their website is reproduced below:

Can I use a bigger motor on my boat than what it's rated for?

It is not a violation of Coast Guard regulations to install or use an engine larger than specified on the capacity label, but there may be state regulations prohibiting it, and restrictions from your own insurance company regarding this.

There are no Coast Guard regulations against exceeding the safe loading capacity, however, there may be State regulations or restrictions from your insurance company which prohibit this. There is a Coast Guard regulation that gives Coast Guard Boarding Officers the power to terminate the use of a boat (send it back to shore) if, in the judgment of the Boarding Officer, the boat is overloaded. There is no fine for this, unless the operator refuses the Boarding Officer's order. We certainly hope that you will abide by the rating, as overloading may lead to capsizing or swamping of the boat.

NOTE: The Coast Guard Capacity Information label is required only on monohull boats less than 20' in length. The label is not required on multi-hull boats, pontoon boats (catamarans), or on any sailboats, canoes, kayaks, or inflatable boats, regardless of length.

That still leaves the state if Michigan? and surly a liability issue if any one was ever hurt.

Rooster Smasher what make and year is your 35hp and what year and make is the 40hp, the reason I ask is ? Well lets say it’s John/Rude but an old girl the 35 and 40 are basically the same motor so it would hardly be worth the effort. But now lets say your 35 is a newer John/Rude then it would be the same platform as a 25hp and a jump to 40hp would be big difference , you know you would be moving from the 25-35 hp to the 40-60 hp platform and I bet you would notice the difference, or in other words you would really be bolting on a bigger motor not just, carb, exhaust.

I dont have a 35 Hp. Right now all I have is a 20 Hp... The 20 Hp I have is a Marinier. The 40 Hp I am looking at buying is a Marinier also. It is a 1989 short shaft.

I just have a hunch the 20 will not push it how I want it to. I will be doing a test run this coming weekend. If it is not enough push I will be looking to put something with more Hp on it. Used 30 and 35 Hp are hard to find set up as a tiller.

This guy will let me test it on the boat before I buy it. So, I will run my 20 hp and see, then run the 40 hp.

Thanks for all the input.

I don’t know what make or year your boat is but if they made the same hull with a remote setup the max will often be higher, Danger on this site has an old side steer 16’ with a 40 John/Rude big twin and in my opinion it’s about correct, I’m sure a 25 or 30 would push her but the 40 is nice, never any trouble getting on plane with all the stuff he likes to take along ,and she runs about 30mph

I've been boarded by the Coasties at Port Huron the last two years while walleye fishing in May for one of their "voluntary" safety checks, and they did look at my rating plate when they did the walk through, and counted up people on board, etc. I didn't see anything on their check form they gave me about the hp rating though. so I can't say whether they really cared or not. They were more concerned about life vests and other required safety equipment, and that the boat wasn't overloaded.

More power! :evil:

Have you guys that fish the Detroit River seen the Border patrol boat? That thing has three verados on the back and is wicked fast.

[TONGA]

“well if some is good then more must be better!”

[POLARBEAR]

If you an get a good price on a 40 take it....You dont always have to go balls out. I would just be sure that it didnt out weigh the 30 by to much.

[wbones9]

buy the 40hp. keep your eye open for a 30hp cowl or stickers and swap em...

[Topshelf]

My old 70's era 16 ft Alumicraft does not have a HP tag on the transom. Came that way. The new baots rate are rated at 30 hp I believe? So what would they do if I had a 50 hp on it instead of the 25hp Rude? Nothing they can do.

FYI: My boat runs about 25mph with the 1978 25 hp rude on it with just me in it. Mine has 4 bench seats and is a deep sided, semi V. I installed one of those Dole Fin hydrofoils on the lower unit and it made a HUGE difference out of the hole and planning. Worth every penny of the 10 bucks it cost at Tony Marine in Marine City area.

[jpollman]

I don't know why I didn't mention it earlier but something just dawned on me. About two years ago I sold a 16' aluminum boat that I put a 1961 40hp Evinrude Lark III. It was a heavy beast of a motor but worked perfectly for that rig. It got on plane very well and I could even troll with it. Personally, I think a 40 is perfect for a sixteen footer.

[Garygreybucket]

dont know the width of your boat or what its rated for, but I bought a 16ft smoker craft last year from spicers it came with a 50 hp and I think I could go up to a 75 or so but the 50 merc does just fine
