'59 Super sea Horse 35 HP vs.'62 40 HP RK-24

[78whiteorbs]

I have a '59 35 HP Super Sea Horse ,and have been offered for a very reasonably price a starter ,generator ,carb, and toothed fly wheel from a 1962 40 hp Johnny model RK-24 Will this work? I do not know what model mine is,it has no ID plate. I know that alot of these era Johnsons are very interchangeable. Also my '59 is a pull start only (as far s I know ) but I am guessing that electric start should be an option I could add. Do you have to have a certain mounting bracket as well (or belts or any of that other jazz)?

$40 bux for the aboved mentioned parts ,really cheap I think but do I need em and more imortantly would they work.

If your 35 is really a '59 it is a RD-21. A '62 40HP is a RD-24, not RK-24.

The parts from the RD-24 will probably work on your RD-21, but not be enough for a complete conversion to electric start. You would still need the solenoid and wiring harness.

pics of the mounting points for the starter would help also

i've got a '59 super seahorse 35hp with electric start. it's RDS-21B. assuming the "S" meant electric start. not sure what the "B" means. anyway, i'll try getting some pics up for you to study as soon as i can...but i'm out of town till after christmas.

The flywheel nut torque is signifigantly heigher on the 40.60-65 on the 35
100-105 on the 40. May just be the nut size but bore may be bigger as well.

The 40 flywheel will not fit the 35

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

Well thad'd be a deal breaker then, if I found the right toothed flywheel would the starter teeth be the same ,meaning would the generator and starter be worth buying from the guy? Are those parts interchangeable?

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

F_R is right. The flywheel will not work, but everything else will. The flywheel on the 60-61 will work, but 62 and later, the crank was redesigned. The first two years of the 40, were nothing more than a '59 35 with bigger pistons. Unfortunately the cranks twisted too easily and flywheels broke off, so they were recalled. When they redesigned the crank, they made it bigger and made the compression lower.

FYI - the "S" in the RDS-21B model number is for "S"uper Seahorse, to differentiate it from the standard Seahorse model. The Supers had the silent package exhaust housing...

Thanks for clearing that up fellas. I now remember reading in the book "Cheap Outboards " to avoid those year models ,now I remember why! There is a plethora of knowledge here and I am learning much ! Thanks guys

Would this work? Found this on ebay, looks kinda rough but the starter would mount in the same location on my '59 right? Would this flywheel work?

up close pix if you scroll down.

Also if anyone lives in Oregon I am jealous , look here,
I have this same motor but not looking as nice cosmetically at all . Twins would be awesome just look how nice she is ...

$50 dollars what a screaming good deal! Wish I could talk the guy into crating it ,though I think it'd be rather expensive to NC , any thoughts?

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

Hmmmm, this old 18 on Ebay looks close to me.

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

Keep in mind that these systems put out enough to maintain normal lighting
etc.But nothing at idle speeds and something like 8 or 10 amps at speed.
Useless for heavy use like trying to maintain a trolling motor battery.I believe there is a regulator required as well.

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

The 33s used the same heavier duty crankshaft as the 40hp, so no, the flywheel will not work. You need a flywheel from a 1960 or earlier 30, 35 or 40.

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

1946Zephyr you lucky dog! Wish I was up that way or I could find someone to pick that up and ship it.I wonder how much shipping'd be ?

Chinewalker ,thanks for the info.

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

Holy sh*t. It's still available. I just sold a computer tonight on Ebay for more than what he's askin for that motor. Too bad he's down by Ashland.
If you sweet talk him and convince him you're an antique enthusiast, maybe he'll work out a shipping deal with you. I think these 18's are about 80 pounds bare.

That's a sweet 18hp longshaft. Too bad it's been in salt water...wouldn't want to pull the LU to change the impeller on that one. The 33hp in NJ is a rust bucket...makes me shudder to think about shearing bolts on that one...bound to happen.
78whiteorbs: what model number is your 59 35hp? I have one in the shop, that is a parts horse. I'll check later today to see what model it is. RD-19 or RD-20 I think. I'll post back later today...not using that flywheel.

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

TM I am uncertain of the model number as it had no ID plate when I got it. I only know that it is a '59 35 HP that is a pull start . I have pix of the engine if you need to see 'em. Appreciate the though.

I was looking mainly for cosmetic parts as I have a nice '57 that has only seen lake water but does not look nearly as nice at all. Funny thing the ones that look like beaters seem to just run forever and the pretty ones ,well kinda like women I guess! LOL

I emailed the guy asking if he'd just sell me the cosmetics stuff,cowling, etc
but have yet to hear back from him. The paint still looks amazing on that one though, huh?!

Re: '59 Super sea Horse 35 HP vs.'62 40 HP RK-24

ChineWalker, if you use the same handle on ebay then you have sold this guy, with the sweet Johnson for sale, alot of stuff! small world....looks like you are a real wheeler and dealer!
