1957-1962mccolluch oil ratio?

[blot101]

i have an old (what i assume to be) 1957 60hp mccolluch. i cannot find a manual. what should the oil/fuel ratio be?

man, i would appreciate any answers.

also, any other information about this motor is awesome. i'm trying to restore my old glastron, and it's original to it (as i've said in other posts)

unfortunately, i'm new to the outboard game and this particular motor has little to no information available

it turns out the days of walking into a shop and asking if they have a part similar to the one in your hand, and having them know is over.
now they have to know where it came from, all the information about it, and if the computer say's no, it's no.
it's frustrating when you have an obsolete part that you need.

yes no?

thanks for any advice/ info.

also, so everyone knows

lesson learned: when you buy an old outboard motor, before you try to fire it up, make sure all the obsolete parts are protected. example include: clean out the carb, take off the spark plugs, and rotate the fly wheel just in case it's stuck in that position.

the fact is, i could've saved myself the hassle of trying to find an obsolete part by freeing up the pistons first. instead i let allllllll the smoke out of the starter ( you're supposed to keep it in you know... and on the wires in the form of plastic)

First The Scott guy at "ask the scott guy" should be a lot of help.
The 60 first appeared in 58 through 60..60hp @ 4,800 rpm.63.27 cu. in.Champion J4C plugs @ .035,points set at .020.If you get us the model number we can tell the year. something like 332,332A.
More later.

Re: 1957-1962mccolluch oil ratio?

the number i can find say's 432-3165 i assume it's the first three?

i haven't been able to find the year of the boat either. so i'm excited to find the year of the motor, it'll probably be the same...

i appreciate the information. with this particular motor, the best i've ever got before this was "good luck"

432 is a 58 long shaft. These have a battery ignition like cars of the time.Belt driven Distributor combined with a generator.Belt tension adjusted to 1/16-3/16 deflection midway between the pulleys.by shims at the upper generator bracket.My old ABOS aftermarket manual has 22 pages covering the 45,60,and 75 hp motors.Fuel mix is 16:1 These motors had their share of service bulletins that the Scott Guy may be able to help you with.
I'm sure he may have a suggestion for an upgraded fuel mix if any.

Re: 1957-1962mccolluch oil ratio?

I have had a total of 5 Scotts (still have 2) and have ran them all at 24:1. I experimented with the 1st and started at 16:1 and slowly moved the ratio up. They still smoke pretty good at 24:1 but I don't have the nerve to go any higher. Overall they were a well made motor. Some of the quality of the exterior metal is questionable. I have broken 2 tiller handles and they don't weld well (pot metal or something). Anyhow if its got good compression it's a keeper. And this forum and the Scott guy are a great asset.

Re: 1957-1962mccolluch oil ratio?

i've been so close to giving up on this motor. it definitely has good compression, the biggest problem is everything on it is obsolete, so it takes me three days to find a place to overcharge me for a fuel diaphram. (actually, i haven't found a place for that quite yet...)

i had to send the starter in to be rewound, and parts of it have been welded back together.
everyone at a boat repair places hate when they see me. i go in to ask about how things work, but they don't really help.

here's and example:

is there an external pump i could hook up to my fuel line, so the diaphram is unneccesary?
answer: "even if you knew the pressure it was supposed to pump, they probably don't make a pump that small, you would almost guaranteed flood your engine. not to mention all the alcohol in fuel these days would ruin anything rubber in your motor, you're spending a lot of effort on something that's worth ten dollars"

well, is there...

*inturruption* "i'm sorry, there's nothing i can really tell you, i have no parts for your motor, your best bet is the internet"

The mechanics are not meaning to offend you but they are right. How much time do you expect them to spend helping you with an obsolete motor, while they need to be working and making money? You really have to love working on boat motors to have one of these things and the internet is the best bet for parts because they are obsolete. You will find youself making parts work that were not intended for your motor. Gotta live with it or sell it and non-running it's worth $50 tops.


As for a fuel pump you may have several options:

Mikuni makes a fuel pump that alot of people have used to convert the old evinrude pressurized systems. Don't know if it would supply enogh fuel. Don't know the part # but a search will find it for you.

Try this link as well. A 1.5 psi pump should work. It may need to be wired direct to battery as well. There are several models on that site and you would have to ask which one would work the best. I'm thinking that it would have to have positve shut off if wired to the battery so it wouldn't run all the time. If wired to the motor somehow it probably wouldn't be required as long as no power was supplied if the motor wasn't running.

The two-stage McCulloch pump specs are 6-9 psi @ 5000 rpm with the tank 30" below the fuel pump. Less PSI at lower rpm.

If the Scott Guy can't help you with a diaphragm, you may wind up making your own. He certainly can help you with a service manual.

BTW, if my math is correct, that thing will burn roughly a pint of gas per minute at wide open throttle. That's a lot of fuel to move.

Re: 1957-1962mccolluch oil ratio?

you really need to talk with the scott guy.I never have but I've heard he is very helpful.As I recall his site is pretty interesting as well.I think they have some high performance McCullochs there.

Re: 1957-1962mccolluch oil ratio?

ok, it's true, they're not meaning to offend. i'm afraid they'll chase me off if i go in there with an engine they CAN help with though!

alot of what you said is true... i've been thinking about how to make a diaphram. the real question is, what is an acceptable material? is real thin rubber ok?

i've emailed the scott guy, and looked over his site, he's emailed me back, and it's true, he knows his stuff. he may have a starter too...

and the mechanics have all been right, even if a little rude. i just hate that everyone has the same story! the biggest problem is i can't see what i need over the internet. i'd really hate to buy a part, and have it be wrong!



this info you gave me is great. i assume this engine being older would burn a lot of gas, but on the glastron, i also assume it's a light enough boat that i won't need a lot of throttle. especially just for fishing.
the external pump shouldn't be hard to wire to the dash or something. in fact, someone changed the position of the key, and left a big hole open. perfect for the shut off switch.

what's the most pressure you think i should have? i mean, 1.5, will it be not enough? or too much?

actually, i guess i'll mess with it if i can't fashion my own diaphram. a lot of people warned me early on that with a vintage motor, a lot of parts will need to be made on my own.

it makes it especially expensive knowing that the starter it'sself is worth more than the engine WITH the starter. but after it's all done, and my first or second year glastron has it's original motor, i think it'll all be worth it for me

Re: 1957-1962mccolluch oil ratio?

You should be able to adapt all most any 2 stage pulse pump with fittings for a hoses to the pulse ports. 1/2 psi at idle 2 psi at 3,000,6.9 psi at 5,000
for the 3 cylinder. length of pulse hoses is critical 1st stage 13" ",2nd stage 8" on 3 cylinder.About 30 years ago I fashioned a diaphram for a 1929 mechanical pump out of an oversized diaphram from a kit for a larger pump.
Seems you could do the same for your pulse pump.The shape appears roughly square in my after market manual.

Sorry I was off on the psi, but that website also has the pumps for the psi you need if you can find anything else.
