Overheating Problems with my Suzuki DT65

[Bigfishtinny]

As Frosty says the paint on the block is disoloured and peeling , it was like this when i got it , the engine ran well , idled perfect thats why I presumed that all it needed was a new impeller as the old one was totaly wrecked. Goes to show when buying a seconhand engine only way to see if there is something wrong is bye stripping it. in a way i'm glad i opened it up as i almost did a rebuild on the motor.

There are many things to see when looking at an old second hand engine. One obvious clue was missed completely (discolored paint).

Nuts and bolts in wrong paces, wires not clipped as standard, new gaskets ( gaskets you can see, engines are painted after assembly), gasket goo, cracked paint on major bolts showing removal, dirty finger marks under the cowling etc etc.

Its actually quite easy to see if an engine has been tampered with, especially if it was an unprofessional job.

But don't feel too bad, buying second hand outboards is usually a nightmare, unless you personally know the engine and seriously know what you are doing.

Thanks for that frosty, I didn't miss the discoloured paint , I asked the seller about it and they said it was normal, and they started it and it ran gr8.... the boat was an absolute bargain it'self and even if i have to spend money on a new motor will still probably be woth it. I am hoping the motor is still ok and will run once put together puerly for the reason i like the simplicity of the old 80's engines , I used to own a 55 Yamaha on a SPortsman Cabin cruiser in South Africa and it gave me many hours of fun even though it was older then me . Although I am considering mounting a small 2hp backup motor on my boat just in case

Since you have fond memories of the old trusted Sportsman cabin cruiser, here it is again. One of many that passed through my shop to have buoyancy flotation fitted and COF'd.

Ugly little boats in my opinion and a bit short on beam, but well loved by fisherman all over the country

LOL thats the one!!!!! Mine used to be green, with an old 55yamaha(very reliable engines) on the back, BTW is that a Suzuki on the back?? looks like the one i am having fun with at the momment

Just remembered mine used to leak so bad i had to get someoen to go to the front of the cabin just to get it to plane and there was no apperent reason for the leak


Gave us a lot of fun times it did though

good spotting and some humor intended - it is indeed a Suzuki 65 on the tail
