55hp yams - Page 2

Well please get in touch if you have a 50hp for sale! Been looking since September now. Nightmare.

And no, the sr4s are only rated to 50hp, I will have to speak to the insurance companies and sea if there is a way of getting around it.

It's definitely not the one off ebay. The one I am looking at is in Swansea.

If you were to sell your 50 how much would you be after?

Cheers

They don't get much above £1200 immaculate, low hours with control box and prop. PM me if you want and let me work out if it would be possible for me to look at it for you. It is a very rare find at that price if it checks out.

Ok well I will wait for pics then pm them to you, where are you based?

It does not come with trim & tilt, which may put you off, but that is not a bad thing on small rib. It's about time I got round to completing it. I would take a 55 with power tilt for it but since that's not realistic just yet it would be around £1200, given the work that would have gone into it.

Really I need ptt because I do all my ribbing off a shallow beach so the ptt is needed for coming in the shallows and loading on and off the trailer. Let me know if you get anything in that has ptt. Thanks for the offer though.

The 50 is not trim and tilt, which is not really a problem on a 4m rib, but it comes down to choice.

As you are aware I am about to put a lot of work into it. I hate to break an engine in good condition but has been neglected.

Honestly, I would take an immaculate trim & tilt 55 yam as I prefer the 55, but given that's not practical until my ones up and running it would have to be £1200. With control & prop.

The pictures are before I take it apart. It does not need to come apart as it's a bottom seal issue, but I wouldn't put it out without being certain it's right.

I launch off the beach and launch and recover at the max pin position with no problems. Also it took so long to post the first time I cancelled and reposted.

There was a 50 yam t&t on eBay with a blown powerhead. It wouldn't be impossible to change the t&t over?? I was toying with the idea myself.

RIB-Teccie · 05 February 2014, 19:20

Hate to say it, the t&t may not be there. Bloody torture.

This is the item number

Im sure it's possible it's just trying to find a donor engine, will have a little scout.

Before it all gets complicated and expensive, I'll keep looking out for a complete 50 as well. You have to make sure a donor engine will come apart and it's not always easy to tell.

Ok thanks very much for the help. Will have to carry on keeping my eyes peeled!

Possibility a bit late now but I was about to pt mine with a ram off a similar vintage 75... The ones with the internal "tilt assist" ram I think are a simple swap, but its been a while since I investigated so don't quote me on that!

Other good thing about then is the long stroke = much torque so can swing a bigger prop.

Are 2 cyl coz that's what everything that size was back then

RIB-Teccie · 07 February 2014, 20:06

There is a way to convert a 55 to power trim using Mariner Rams, any ideas???

I have seen a very old Mariner 60 twin using the full saddle, but that is impractical, I like the side Ram idea better.

9D280 · 11 February 2014, 07:51

Ok, had a wee crawl through my "archive" - There are basically two versions of the clam p swivel / etc on those engines - the ones with the external rams and the later models (only from memory made for a year or so at the end of production)

So, if you have an external ram type you have 2 options:
1) find a set of powered rams and a pump unit. (you can use the pump unit from a Mercruiser leg). You will need to fit an "over tilt" switch otherwise tyou can trim sufficiently far out that the swiel bracket no longer is "caught" by the clamps at the bottom, resulting in the saddle possibly snapping off when you turn.
2) complete swap of the clamp / swivel / PT ram assy. I was going to use a 75. Internal ram you "simply" find a powered ram to suit.

I realised what was confusing me was I have a Yam PT unit on my Merc! There is a confusing mess of parts bin bits at the end of Clamshell production, but I'll leave that saga for another day!

here are the pics of the yam I am looking at, what do you think? I am considering buying this for only summer 2014, then selling it in sept and buying what i am really looking for december because time if running out and prices will jump as soon as it hits march (I think).

He says the white residue is spray grease.

There was some corrosion of the power trim so he quote; ''The silver "pot" on the power tilt was showing surface rust bubbles so I scraped them off & applied rust cure then put glass impregnated filler over the top of that, then painted it with cold galv just to "make sure". No doubt I could have done a much neater job if I had removed it & rubbed it down & resprayed it Yamaha blue''

Looks like it has been neglected, but that's reflected in the price you were offered it at. Very rare find and clearly needs a tidy up. If it runs well in that condition, I would think a good service and a clean up would get you going. If you can knock a bit off the price because of the cosmetics, it would pay for some paint. It may be worth looking at a price for a new trim and tilt motor cover and seal if you were keeping it. If not, as long as the corrosion is not too bad, you would get your enjoyment out of it. You must check the shock mounts though as most outboards are a pig to get apart after a few years. Simply turn engine fully to one side and take hold of the front and rear of the tray, try to push it further than the steering travel in both directions, it should be firm with only slight movement, if it is slack and there is lots of movement, the mounts are shot and you are heading for a large bill.

One of the good points about a neglected engine is that they are usually in one piece and have not received the attention of a willing amateur who is a bit quick off the mark with the spanners, without having the knowledge to use them.

9D280 · 17 February 2014, 13:05

I've either not noticed it while you've been talking or it was in a PM, but in a total worst case scenario where the engine is worth more as an anchor that PT fits a load of other engines between 40 & 90 odd hosses, so it could be easily sold as a standalone unit to recoup cost.....
