Second hand 4 strokes

[will101]

I'm looking at a boat fitted with 2X 100 Yamaha 4 strokes on, which is great, BUT: they each have 1200 hours on them. To me that sounds a bit much although they come with a full service record.

When I take the boat for a wet test, what should I be looking out for, besides the obvious? (knocking, smoking, stalling, rattling etc)

thanks

Before you buy them call Yammaha and ask how much to do the top end on those motors. I dont know much about the marine 4 strokes but on the motor cross 4 strokes to do the top end is a small fortune.

Hiya

Will101, those 100hp 4 stroke yamaha's are incredabily HEAVY. Just make sure the boat can handle the extra weight of those particular motors. They weigh 184kg's, whilst a 200hp Origin 2 stroke weighs 180kg's!!!

On the whole, Yamaha makes a very decent 4 stroke.

The GREATEST downside to a 4 stroke is when they BREAK, its normally cheaper to buy a new motor than to fix them!! Seriously, even a small problem can become a VERY costly repair. So, my best advice, PAY A BOATSHOP, like ANCHORBOATSHOP to give you a report of the motors. It will be money well spent.

1200 hours does seem high. It depends alot on what the boat was used for. If it was used for fishing, was it inshore or offshore? Most tuna boats are driven gently, so as to conserve fuel and rack up big hours very quickly. I put on 1000 hours on my 4 stroke 140hp Suzuki's in one year.  4 stroke motors, just like any other motor, likes to be used on a regular basis. I would rather buy a motor with 1000 hours on it that is 2 years old than one with 700 hours on it thats 10 years old........

Ultimately, it will boil down to the price of the rig though......

Post some pictures and good luck with the purchase!!

I bought 2 yamaha 4 stroke 2 years ago and they run very well,they did need a tune-up . one very important thing is to do is a compression test

shot guys I will have a look at the boat and hopefully the motors check out. It's a scary move... but if it's a good one I'll definitely be rubbing it into Sealiners' faces!

4 strokes are good, light on fuel and dependant and then they are extremely quiet, they also have low down torque.

2 Stroke motors are good, heavier on fuel, very dependant, noisier and that damn smell of the oil. They don't have as much low down torque , but as with all 2strokes, once you hit that "powerband" a 4stroke is not going to give a 2-stroke a go.

I would love 4strokes, purely from the noise and no 2-stroke smoke point of view, but 2-strokes are tried and tested, and my 2x85hps can run on 2 cylinders if need be.

I can't for the life of me understand why the parts are so damn expensive, I really think it's because of the grapevine, some parts are just bloody rediculous, but that's boating for you.

These are just my own views, not based on facts except for the power generated by a 2-stroke.

if car parts (in general) were as expensive as boat parts a Citi Golf would probably cost in the range of R 250 000 or more !
