15HP Suzuki I was going to buy has a seized cylinder...

Hi,
I was offered a 15HP Suzuki 4 stroke to go with my first 3.4m Quicksilver that I bought.
After a long delay it turns out the guy was trying to get his mate to fix a seized cylinder. Apparently impellor had broken too.

my question is how easy would it be to get such a problem fixed...and how expensive?

Otherwise it's back to the drawing board for me I guess...

Damn!!

:-(
PS Thanks in adavance for any response!

'Get his mate to fix a seized cylinder' and a buggered impeller says stay well away. Sounds like it's been heat seized.

Many thanks...so no chance of remachining and new piston etc bringing it back to full performance?...

Good for me to be clear though... cheers!

If it was your own engine and you had minimal budget and good engineering skills this MIGHT be an option - but I don't think many people here would want to buy an engine which had seized due to an overheat - even after repair.

Trouble is, if he's broken it and the impeller is buggered you don't know what other damage the overheat has done.

You could fix it. It's hassle though, and highly unlikely to be worth it compared with buying one that isn't already gubbed.

Many thanks guys..I'll write this off as an option, though was told all was fine for last 4 months... looking at e-bay 15hp options are gonna cost a lot more than 450 notes now though...

Hmmnn...it'll have to be 15hp as I've promised my lad I'll be pulling him and his mates in a donut this summer (& have bought the damned donut! LOL!)

:-)

Once again many thanks for your advice... invaluable to newbies like me!

If you want to tow a donut, you really want a 2 stroke for the extra torque.

ferryden · 01 March 2011, 23:08

OK... though this guy said he'd had good fun with his own lad on a donut abroad last year with 4 stroke set up... hence where I got idea from.
So I'll now look for 2 stroke, though I understand they're scarce due to discontinuing...

How much risk would there be in me using a 20hp if within max boat weight? (they actually seem better value from some ads I've seen...)... main use around a sheltered bay areas rather than open water...

...Oh dear!...I've that Pandoras Box feeling again...

An aftermarket piston is going to cost you between £70 - £200 , depending on the engine (not got time to look yours up, but if you Google "Mallory pistons" and "Sierra marine pistons" (otherwise you get a lot of websites about classic Fords!) for the current price lists.
Word of warning - Don't buy the piston(s) until you have had it bored - the oversize ones come in "step sizes", and you won't know how much metal has been taken off the cylinder until it's been done. The M/C shop will also need to know what sizes are available before they start, so look at the websies before you talk to them.

It cost me around £130 to get my block bored, BUT I dismantled & rebuilt it myself, so no costs associated with the pre / post machining. Also if yours has coated cylinders (no idea about that engine, I know some Yams had chromed liners) then you are likely onto a looser anyway.

Also factor in about another £50-100 for a full powerhead gasket set, which you will need to replace to reassemble it.

On the plus side, you might only need to bore the siezed one, but I wouldn't hold my breath. Chances are if one has gone, the rest won't be too far behind.....

If the boat is rated for it, no risk outside appropriate use of the throttle!
