Ok - crazy idea but what do you think??

  1. I've currently got a 15' ProCraft with a 90hp Rude on her. It's rated for 100hp. I was thinking of doing this - just a thought at this stage.......but tell me what you think??

    I was thinking of finding a 115 or even a 140 hp motor and slapping that on her! I could get some 100hp stickers made up and nobody would be the wiser.

    I realize this isn't perfectly "legal" but I don't think anyone would notice.....especially since newer motors are smaller than they used to be. Correct me if I'm wrong, but the rating is not based on Coast Guard standards or anything, it's the manufacturer' recommendation, right?? So are these recommendations based on weight of the motor on the transom - or maybe the force on the transom under power?

    I can run high 40's/low 50's now depending on load........I can't imagine what she'd do with a 140 on her! I was thinking 70's?????

    Has anyone else ever done this??

    The hardest part would be getting the wife's permission - which is prolly the deal killer. What's the resale factor on my old 90 rude? It's a 1983 model, runs like a champ........and I was thinking what would my payback be on it?? Trying to justify this to her is going to be darn near impossible. HAHA!

    What do you think the cost of a nice, used 140(ish) HP would be and what could I get out of my 90hp????

  2. If something happens to go wrong theres no way your insurance company would cover you....they never miss an opportunity to welch.

    i think there are a few reasons for hp ratings.i'm safety is a major consideration.performance is also an issue.the old axiom "bigger is better" doesn't always hold true.aside from additional weight,performance is a real factor.maximum hp ratings are recommended to get the best performance from a particular boat.going too much over the ratings are most likely going to result in no increase in performance.in fact going almost 50%(140hp)over recommendations may give you better top end speed,but the boat may not be designed to handle it,resulting in poor handling and unsafe conditions.

    why not just put a v8 in her.
  5. Smaller in weight yes, but not HP. Pre 1980 motors were rated at the powerhead, but now they are rated at the prop. That means a new 100 hp motor would have more hp than a 1975 100 hp motor. As Misfit mentioned, that boat wasn't designed to withstand those speeds and forces. Those ratings are there for a reason.
  6. That is a good one.:D:p

    This sounds like a job for the Lake Raider.:D

    I think Dkilla brings up a great point. If something happens I am sure the insurance company would love to claim that you were negligent and not cover.

    If you are that in to going fast then you may want to check in to selling the whole rig and upgrading. I just think there are way too many problems that could arise.

    dKilla made another excellent point if you have insurance.they'll drop you like a hot horseshoe if they find the boat overpowered,and if you have an accident claim......................sorry about your luck,you're on your own.

    if ya want a go fast bass boat,get rid of that sled and get yourself one of these.is 116+ fast eneough for you?:D

  9. But if I read above correctly, the newer motors are actually more HP than the older models - by where they are rated from??

    So if I got a newer (how new??) 100hp motor, then it would have more power/speed than an older (say 1983 100hp motor when the boat was made) motor????

    Am I saying/thinking this right??

    I know 140hp would be just silly.........but 115 isn't totally out of the question. But if I'm understanding right, then a newer 100hp would work nicely, right????
  10. Yeah Allison's are sweet - but I'm not in the market to spend that kind of $$

    To obtain insurance don't you have to provide serial #'s for both motor and hull? When the #'s don't match the HP they will catch it.
    I actually know someone who did this! Had a fish/ski ,an early 90's model,he blew the 115Merc that was on it originally. A relative of his had a 150 Merc for sale,so you know what happened next.............New stickers on the cowl and off to the lake. Found out pretty quick why the boat was rated at 120hp,chines very violently,and is almost uncontrollable at wide open. ie too much HP for the hull.

    IMHO,I think your just asking for trouble exceeding the recommended HP.
  12. Motors made after somewhere around 1980 are rated at the prop, where it counts. Before that, they were rated at the powerhead and some of the horsepower is lost before it gets to the prop.

    The last time I was checked by the Shore Patrol they checked the capacity plate on the boat and the spec plate on the motor. They did not believe the numbers on the cover. They do this locally now because there are alot of guys on 9.9hp only lakes with a 15hp and a 9.9 cover. If you buy a newer motor and have to register it, the registration will have the HP listed. If they check your capacity plate and your motor is above the max rating they will escort you off of the water. The same goes for overloaded on weight/people capacity.

    The second reason I would not recomend it is the dollar to speed ratio. You would probably be spending a few thousand dollars to go a couple of miles an hour faster. Its been said already but upgrading to a faster boat is safer and probably less expensive in the long run. Just my opinion for what its worth.
  14. Yeah, I was just wondering what the opinions on here were........and there's alot of valid points I didn't even consider.

    Hopefully I'll be upgrading to a new(er) boat next year........my dream is a 21' triton w/ 225.

    By the way, you stated that the same goes for overloaded weight/people capacity - how do they check for this? Do they make you step on the scale or something? HAHA!!!!

    ask lakeraider:D
    he got busted before even getting on the water at cowan a few years ago,LOL.he was short one pfd and when he told the ranger he could get another one,she then proceeded to check the capacity plate and ask questions.even after a litte fudging on the weight of him and his passengers,she wouldn't let him on the water because they exceeded the weight limit.
  16. That's funny! poor guy!

    I'll tell you what..........(knock on wood) I've never had a run in with the rangers yet. Last year at Seneca I got inspected but all he wanted to see was my life jacket - make sure I had one.

    I've got all the safety gear, but one thing i've been putting off is strapping down the batteries. i've got them secured, but not in the black plastic boxes and tied down that way. need to get moving on that!

    Your capacity plate will say how many people can be on board and how much the total weight can be. The rangers have seen thousands of boats just like yours and mine and they have a very good idea before they pull you over.

    Youre ID's will say the height and weight of each person on board. You can actually demand to stand each person and all of your gear on a scale. They will let you but you will be on the bank when they do it. If youre right you only lose a good day of boating. If youre wrong the ranger will be alot rougher on youre wallet than he was on you.

    Most of the big deep cavity inspections occur on the big three. Memorial day, July 4th, And Labor day. On those days the rangers are on the lookout for rule breakers and they have dealt with 300 rule breakers before they get to you. They have little patience for any one that wants to be weighed at the dock with scales.

    With the tied down batteries ive had no trouble. It seems to me they will accept either a tied down battery or one in a case. Mine are in a case but are not tied down. I think fire will come either from fuel or spark. If its fuel i get the fire extinguisher on my way out of the boat. If its spark then i yank out the batteries and disconnect them both. Again just an opinion for what its worth.
  18. I just got my boat inspected by the coast guard. Doesn't cost anything and they give you a sticker that the rangers like to see on your boat :D I have my batteries (both the one being used and the spare) inside a battery box and tied down. You don't want to take any chances on it falling over or anything shorting out those terminals....

    Here is the capacity plate/hp law from the ODNR

    "Capacity Plates
    (ORC 1547.39 & ORC 1547-40)
    No person shall operate or permit operation of a watercraft in excess of any of the stated limits on the capacity plate. When no capacity plate exists, no person shall operate or permit operation of a watercraft if a reasonably prudent person would believe the total load aboard or the total horsepower of any motor or engine presents a risk of physical harm to persons or property.

    No person shall alter, remove, or deface any information on the capacity plate. "
