  • thinking of buying a 1990 100hp suzuki v4 but have a question first

    i found a 1990 100hp v4 suzuki, the guy says it needs the guages hooked up in the boat for the motor to start..... i have had a few suzuki outboards and have never had to have anything hooked up for them to start, the motors i had ranged in years from 86 to 92 and like i said..... all i had to do to start them was put fuel to them like the older omc's, if anyone can shed some light on this before i go for a long drive and buy it that would be great..... thanks in advance

    noone has any ideas about this? this guy says its a safety thing that the motor wont start without the guages but that sounds like a bunch of bs to me, its an old motor, i cant see it needing them to run

        Maybe he is talking about the killswitch on the remote controls, I also kno that some models had an external kill switch for traveling offshore ...

          im not sure, he just said it needs the guages hooked up to run. from my experience with them you dont have to use guages at all until 1996 and i agree with your quote 100% THE MAXIMUM HORSEPOWER REALLY ISNT EVER ENOUGH, that is just a guide for people that need someone to tell them whats safe hahaha, my chrysler conqueror is only rated for a 75hp but i have a 115 yamaha on it and still think it could use a bit more ( im only getting 62 mph out of it ) on an unrelated topic, how to i advance from being a cadet to something else?

            it is just post count.
            Keep posting good info and help to others and you will move up

            by the way boats have limits on them to make sure the transom strength from force of HP and weight of motor will not cause problems. If you run more than that your insurance may not cover you and your boat

              i dont disagree with what you are saying 99 yam 40, however my chrysler conqueror has both a US coast gaurd rating and a canada coast gaurd rating on the same tag from factory, the canadian one says its rated for 75hp and the us one says its rated for 105hp, over the years i have owned at least 80 or more boats, i have had 2 boats in my yard at the same time that were identical in every way other than the name on the side was different, i had a 14.5 foot sunray that was rated for a 65hp and a chestnut ( identical in every way ) that was rated for a 30, i do realize that by going over the maximum rated hp that insurance will not cover anything, all i am saying is that i have found that alot of boats are built pretty well the same, the transoms were mostly all built out of 2 pieces of 3/4" douglas fir plywood, glassed to the sides of the boat so if one of them will take 80hp, so should the other, i had a 14.5 ft peterborough that was rated for 40hp, with a 40hp on it, it wasnt much fun to drive so i put a 90hp on it ( just as an experiment ) and it worked great ( that was 6 years ago and the guy i sold it to is still using it today with no damage to the boat, and the boat only sat about 1.5" lower in the water with the 90 compared to the 40 ) im not trying to makes waves by saying what i said all im saying is everyone has their own opinion on hp ratings and from my own experience with it, this is mine, i just rebuilt the transom in my chrysler with 2 pieces of 3/4" douglas fir and covered that with 2 layers of kevlar ( which will make the transom much stronger than from factory ) its rated for 426 pounds of engine weight so i should be able to put a 175hp evinrude 2 stroke on it and have no problems, im not saying i am going to, just saying that i should be able to ( im not crazy i just like going fast ) anyhow thats my opinion hope i havent offended anyone with it, thanks for the reply

                looks like you have run through a lot of boats.

                No one is offended , Just saying insurance may be a problem covering a boat if not properly rigged

                    yeah the insurance thing is optional here in nova scotia, a couple years ago i had a 15ft checkmate ( my profile pic ) when i blew up the 90hp that was on it, i put a 140hp suzuki on it ( it looked as big as the boat ), every time a cop saw the boat i was worried they would say something about the engine size compared to the boat but all they ever said to me was " catch alot of fish with that?" hahaha, i always felt like saying " kinda hard to catch fish at 80 mph" hahahaha

                      Buy a GPS. Your boat doesn't run 80. I have a DT 140 myself and it is a straight 4. I have never seen a Suzuki V-4.

                        that was a straight 4 dt 140 and on gps it topped out at 77.4 mph ( thats close enough to 80 ) and the 100 is a v4, i looked at it with my own 2 eyes and it was the first one i ever saw, oh.... and i had a few mods done to the 140 and the boat to get top speed out of it, just so ya know Checkmate Enticer, and i read all my speeds on gps ( speedos arent accurate enough )

                          Good to know. Is that an MX-15 you have? Maybe I came off the wrong way, I know those are good runners, I just didn't know THAT good. Curious as to the mods done to the Suzuki? Reeds, heads shaved? Also curious the prop you are running because I'm having trouble finding a good selection of props. I'm maxing out a 22" Turbo prop now. Thanks, Scott

                            it is an mx-15, that picture was with a stock 90 evinrude on it, it would max out at 48 mph with a 21p prop, on the suzuki i had the heads planed, a different set of reeds, i made a forced air induction for it, jetted the carbs to get more fuel because of the extra air it was getting and had the cylinders ported and polished ( this stuff doesnt cost me much to do as my father in law is a machinist, i was running a 25p four blade carbon fibre prop on it, before i did any work to it i was getting 68 mph with a 21p three blade aluminum

                              Nice one! I mod a 30hp 3cyl Suzuki to the max back in the day, had to run it on AVgas .... I took out the 70hp guys, what fun that was!
