Suzuki 55 2 Stroke - Page 2

Edward Harrison · 08 June 2010, 17:10

Hi Chaps,
I have checked the prop and the numbers are as follows - S1400 and 11 3/8 x 14.
What does that tell you about the engine. Prop looks very well kept and pronounces that it was made in Japan, so may be the original?
The serial number is 05501 012235. Can you date it from that, DHD?
Also, I have a Honda key switch fitted and the Suzuki kill cap, but so far I cant find anywhere closeby who keeps those items. Any ideas where I can get them at a sensible price online - I would be mad going out with only one key and kill cap!

Your prop is a 14" pitch. I reckon that may be too fine for a lightly loaded SR4, but give it a run and see what max RPM you get.

Your motor is 1990.

Could you get the key copied in one of those stalls at your local market?

For a replacement killcord, try IMS, as I suggested in an earlier post. Failing that, you may have to ring a few Soozook dealers to see if they have one in stock. They haven't been used for around 15 years though, so you may struggle to get hold of one.

Thanks DHD, I will google IMS and see what I get.
I cant check on revs as its got no counter on it. Are they easy to find and fit?

Rev counters are easy to fit - cut a hole in the console, fix the tacho and run a cable to the black & yellow fly lead coming out of the control box. If you want to be really posh, you can wire in the light so you can see what RPM you're running at in the dark.

Did someone mention cutting an ole?

You'll Be OK towing skiers then - my old SR4 had a Suz 25 of similar vintage & ran fine with a 13" prop!

If the carbs are similar design to the 25/ 30, there is a "wot stop screw", which I suspect won't give you much more than a couple of HP drop, but if replaced by something longer......

Alternatively, some versions of the control boxes have multiple holes for the throttle cable - you may be able to miove the connector in a pin or two & limit the cable travel a bit.

And welcome to ribnet!

(in the following paragraph, I;ve had to replace the [ and ] symbols with { and } sdo as not to confuse the computer.I'll use this as an example)

The text of the post you hare quoting shows up in the box you type in lookign like this:

To split it, use "copy - pase" copy the bits in square brackets to the beginning & end of the text. and treat it like any other lump of text, e.g. deleting extra stuff not relevant to your comment etc - example:

{QUOTE=Edward Harrison;356007}

Bit where you type your comment

{QUOTE=Edward Harrison;356007}

Different motor though, so you're not comparing like with like. In spite of this, I agree that a 14" pitch prop will be fine for skiing, but the motor may over-rev if the boat is lightly loaded, hence my suggestion of checking the RPM at full beans.

Edward Harrison · 09 June 2010, 22:38

Thanks guys for the help.
I have the control box in bits and have ordered a SS plate to cover the nasty hole in the dash where thge bakelite switch plat went. Will sort a rev counter shortly. Still struggling with the trailer though. May get it changed for one withy bunks. I think its just too damn big for the SR4.

My point was that if a 25 can push an SR4 along with a 13" prop happily, an engine of more than double the horsepower will have no problems, with or without a skier on the back.

I gotta start posting more concisely.........

What max RPM did you get with your 25hp?

Edward Harrison · 10 June 2010, 10:21

Hi DHD
I tried IMS and they are coming back to me.
I found IBS in Cornwall, but the numbers listed are all wrong and go to another business who are fed up with calls for IBS! I have emailed them but with no response. Can you advise a number for IBS? Also, their website address does not work either. Are they still in business?

No idea. never had a tacho on that one. it wasn't screamiing like the yam did as it passed 6K

, nor did it sound like it was labouring.

Not very scientific that, eh?

Probably about right, though.

IMS (International Marine Supplies) are who you want. I've always dealt with a bloke called Chris, who is very helpful.

IBS is something to do with having the $hits.

I've got exactly the same motor on my 5.5m DSB rib. Now on my rib it's not the fastest but it's a great reliable motor even for it’s age. I was told the same as you that they were plagued by electrical problems, so as a precautionary measure I replaced the oil and water flow sensors (I found the water flow to be badly damaged). I then gave it the full works by giving it a very good service, but in fairness to her previous owner he kept it immaculate.
I got an original Suzuki manual with my boat & motor and it was the best thing ever, it gives you a step by step guide to EVERYTHING!
Yeah, International Marine parts are great! I got all my stuff for them (inc. a spare kill cord!).
As someone previously said, go onto Brown’s Point Marine Service website (http://store.brownspoint.com/dt55/558897.asp)as they have the full parts breakdown with part numbers - International Marine Parts can then easily supply them.
This is my 1st boat and I find it a very easy motor to work on!

Edward Harrison · 10 June 2010, 21:47

Hi Steve,
Excellent information thanks. I, too, have got hold of IMS today, and found them very helpful. My engine looks pristine under the cover and seems to have done few hours despite its age. I will try to get a manual - perhaps from IMS - and follow your advice. I did manage to order the kill cord caps today - thanks to all your help on this forum.
Thanks again,
Edward

Here you go:

I know the seller: tidy bloke (despite being a bit of a jack

)

Edward Harrison · 11 June 2010, 09:24

Hi DHD,
Thanks for that. I will make him a bid.
Edward

Downhilldai · 11 June 2010, 11:03

Good luck - check it's compatible first. The seller used to be a Soozook dealer, so will know the answer. It looks like it's from a 2-stroke, so you should be ok.

Hi DHD, I cant get the guy to answer he question re the suitability of the gauge for the 55. I wont bid on it as its not sounding good. He wanted £30 which is fair, butno good if it wont work!
