Best place to buy Merc Engine rebuild supplies
 

Does anyone offer high quality master overhaul kits for Mercury Racing Engines?

Specifically 525 SC's. Or do I need to piece it all together myself. Looking at potentially rebuilding some 525's and will need gaskets / bearings / maybe pistons / cams, springs & Lifters (I'm thinking Bob M.?) / oil pumps, timing sets etc.

I would also Like to re-seal and replace the bearings in the blowers. I'm trying to work up a budget for planning purposes. I have the machine and assembly work covered, but need to shop around for pieces parts.

I searched around on here a bit, and it looks like other than roller cams the stock set-up is pretty much the best all around package. Any other tweaks or updates I should plan on? I'm looking for reliability above all else.

Thanks :drink:

id say calling bob m would be a good idea,he can probably fix you up with everything you need.

Cool, I'll give Bob a call.

Hey artie, what are you selling ? the formula or the cig. ??????? happy new year !!!

Hey Jim! All of the above! :lolhit:

I actually sold the cig a few years back to a very good friend who unexpectedly passed away just after he bought it. I have been storing and taking care of it for his widow, and it is for sale.

The Formula is also for sale, and I may have a new project lined up, hence the need for some 525 parts :whistle:

Happy new year to you as well!

The rear bearings and seals can be a issue on those blowers. If your getting fuel in the rear oil housing, its time for seals and bearings. I got mine from local bearing supplier. Easy Job. Rear cover gaskets are available from summit or places like that. Check the snout bearing too while they are off.

If you end up needing to bore them, I'd personally lose the dished pistons, stick JE flattop supercharger pistons in there, and go with roller cam/lifter/spring kit from Bob. You''ll end up somewhere around 8.2-8.4:1. This will help the little blower out a bit, over the stock 7.6:1 or whatever it is.

A head stud kit and MLS headgaskets are good to do while in there. For the money, rather than rebuilding your stock rods, upgrading to a H-beam rod like a scat or eagle, with ARP 2000 Bolts, imo is money well spent. While the stock rods are plenty for what your doing, you might have 400 bucks in recon'ing your rods, while for another 400 you can get new and much better rods. Ebay your good used rods for 100 bucks each set. Now, youre into some H beams for a deuce. Especially if your doing new pistons, the full floating H beam is the way to go.

Thanks for the info MT. I am definitely going to replace ll the seals and bearings in the blowers so I know I have freh units. How do these engines tolerate 89 octane? Is it a lost cause to try and make them 89 friendly? If it is i really like the idea of bumping the static compression a bit to gain a little grunt. I would love to do the h beams, we will see how the budget treats me. I'm not looking for big numbers, but I am a fan of building a stout motor. Overkill is almost enough in my book :)

Have to plan a budget and stick with it since I have three of them to build. :silenced:

Ewwww..... Triples.....that can get pricey. In that case stock refresh! :cartman:
