Title: Mercury 950ss
Post by: Shirley 2 on November 20, 2017, 04:39:24 PM
Hi all,

Have just been given some bad news on my 950ss Mercury... the block has rusted through number 6 cylinder and it needs a full powerhead restoration. Anyone recommend where I can get this done, or at least a place to start?....

Thanks in advance,
Pete

Hi Pete,
I'm not sure if I shared this info' with you previously? Your motor is a 1967 model. I recall you are located in Orange NSW. Do you have any pics of the damage?
I suggest you keep an eye on ebay/Gumtree. There is a rather wide range of HP and year model power heads which will bolt up to your current midsection.

Years from 1966 to 1969. Perhaps even 70 & 72, I have to check?
HP from 65 to 125.


Finding a motor in great nick from the West shouldn't be too difficult, I feel. Keep looking and post all the details of what you dig up and I'll try and assist you.

MERCMAN.

Thanks Mercman - and yep, from Orange NSW. This just happened on the weekend... she turned 50 what a way to celebrate! I'll send through some photos tomorrow, and if you let me know what fits I'll scour Ebay and Gumtree.

Thanks again,
Pete

I have an idea. I can get my hands on a 1975 1500 Long shaft. Apparently it is ceased. Although, I'm sure it has TNT.

Currently on ebay in the USA is a overhauled 90hp block and another listing for a 115hp block which either will bolt straight up to the lower half of the 1500. https://www.ebay.com/itm/Mercury-Outboard-inline-6-1150-115hp-Overhauled-Powerhead-Warranty/162725389526?hash=item25e33064d6:g:QbMAAOSwBjdZ8KKG&vxp=mtr

All we need do is remove the carbies, flywheel and fuel pump and lines, along with the electrics from the 1500 and then add them all to the 1150 block. There may be a way of even grafting your old cowls on to the result. If not, you can easily place new 1967 decals on to the 1974 cowls.

Thoughts?

Mmmm, nice work! The runabout is only rated for max. 110... so would that extra hp be an issue? Certainly worth me thinking about - thanks. On a different tack, what are your thoughts on overhauling the powerhead I have? Is it possible and do you know anyone to recommend?

Extra hp is never an issue, no one will know what's under the bonnet if your fitted that block !

As for your powerhead, that's why I requested to see pics of the alleged damage earlier. Lets' see how bad the damage is first. You can send pics to my email address as well. That may show me a little better detail.

Recently, I repaired a torn fuel pump diaphragm in my own single banger 4hp Yamaha, with Loctite branded superglue. It's still working like a little champ!
The interweb wanted USD$69 for an entire carbie gasket kit. Far out.
