    I found 319 lbs for a 2000 90hp Johnson from searching and 250 lbs for the 70, same year. I am hoping that is close to what you were looking for

    this is a good thread for this ? I have a old 66 fiber glass boat w/ a huge
    66' 60hp motor on it. I seen 70s and even 90s smaller then my motor.
    my boat is rated for a 60hp motor. I dont know the weight of the motor, but can I upgrade to a bigger motor or should i stick with the 60s?

    this is my first boat, and didnt know motors cost so much. I even thought about going down to a 40 or 50
    heck they'll still dig a hole in your pocket

    Catfish Willie,

    I have a 1760 roughneck that is only rated for a 65 hp motor, when I purchased the boat it already had a 70 hp johnson, and I just put a 90 hp mercury on it. I have had no problems with it at all... You should probably try to find out what your old motor weighs and compare new motor weights. My boat is an all welded boat, so I didn't hesitate to do it. Call (D&J marine)Dave Book in Oregan MO. He will tell you if your boat can handle a bigger motor. PM me if you what his #

    In oklahoma, the lake partol will ticket you, and escort you from the water if you have a motor larger than the rated motor on your vessels data plate. The boat may handle the motor, but can the law?

    willie , from what i understand about the 66 yr. model , the hp rating came from the power head ................. the newer engines , say 1985 and newer, are rated at the prop ................ so a 50 hp new engine is 50 hp at the prop ................ the 66 60 is probably no more than 50 hp at the prop......

    Weight has nothing to do with why a boat is rated for a certain HP.

    Don't plan on insuring the boat if you've got an over rated engine.

    In Indiana if your boat is over powered and you are caught you are in deep do do. Get your check book out.

    How do they determine hp rating. I have an 96 20ft roughneck and the max rating on it is 90hp. I'am currentley running a 140hp evinrude without any problems.

    What other states fine you for oversized motors? I have a 16-48 Lowe that is rated for 35hp, but I would really like to put a 50hp on it. This is a very perplexing situation.:confused2:

    Back when they first changed it,a Mercury factory rep told us the industry "average" was .07% "IF" my memory is right.I do know that he said it varied from makers and models.He said that different folks were measuring in ways that were best suited for them and the rules were changed to make all use the same standard.

    From a game warden."Illegally overpowered boats leaves you in bad standing with the Judge,juries and your insurance company"."It can leave you in violation of your insurance policy and therefore with no insurance though you are paying for it"."Many are under no obligation to insure someone while they are committing a crime".

    Commercially licensed fishermen had no engine size limit in Georgia when I commercially fished.Good rules for good reason.You may need a 300 hp on a small displacement hull that will not plane to pull a load.Perhaps 10 knots max wide open.The State & US Coast Guard can still get you if they consider your rig unsafe.My normal boat insurance did not cover me in such either and I had the recommended HP.motor on my boat.

    High Speed killed most in my life on the water during my later years.Not all,but most.I seen folk on here who consider themselves responsible folk brag of running high speed at night with a spot light which blinds all oncoming boaters and is illegal.

    "Out the slot crap and the brags of such puts a tremendous strain on a boats transom with a big motor.A boat is designed to operate and handle at certain speeds SAFELY.I watched a 14'x48" john boat flip in a wind gust.The motor & boat was new and bought that day. 9.9 Mercury.The guy weighed about 140 lbs.I had it almost happen to me in the same kind of rig.Weight can also hurt.Your information plate takes both in consideration along with the manufactures insurance companies rating.He does not set the rules for his insurance company.They set it for him.HP itself hurts nothing until it is abused.If you could put a 500 HP 50 lb.motor in the back of a 14'x 48" John boat and only use 5-10 HP you would be fine.

    Game Wardens and the Coast Guard are very good at picking out violators at long ranges.They see millions of boats and motors in their career.They can ID you way off with their optics.They know that there is no reason for a recreational boater to have a illegal engine except to abuse it and the law.You don't build a hot rod or boat to cruise legally.

    One of my all time favorite things is watching a fast boat outrunning the Coast guard and suddenly watching their reaction to that strip of spurting water that catches up and then passes them.ALL STOP.There ain't a moron on the water that believes that they can outrun that .50.And once that happens,you explain it in Federal Court,not to the Coast Guard.You had your chance to talk to them before the water show.It really don't look like much,but it is far more impressive than anything that Los Vegas ever put on.I have been told that it is a "awesome thing to watch passing you"."Expensive and also time consuming when you lose your boat and serve time too".

    You local fish & game and the US Coast Guard can help you.They tell you like it is.I use to love to watch people try to tell them how it "was going to be".Remember that the OPERATOR is responsible for all that goes on on board.Things such as motor size can often mean the difference in life and death.Too small can be dangerous too.Please think about it real well before you do anything.

    I love you Brothers and Sisters.peewee
