I just bought a Super Seahorse V 75 I don't have the serial number or other information on it yet, but I think it's an early 60's. Good or bad motors. guess I should have asked before I bought it.

Never seen a bad Johnson, just neglected ones, but one never knows. Find some numbers on it, and more can be told

There should be a plate attached to the port (left ) transom bracket with the model number. Get that number to us and we'll be able to tell you what you have.

Also, there should be a small core plug on top of the block, near the port cylinder head gasket with that same model number.

Just my opinion if its electric shift Witch im pretty sure it is.. Its not a great motor. Also the old Johnsons didnt produce as much horespower as they were stated to.

Re: Super Seahorse V 75

My personal opinion is that there's nothing inheritantly wrong with the electric shifts vs manual shift. OK, so they are expensive to repair, but try checking on the prices for a manual clutch dog and gearset. Worst part is nobody wants to work on them, either because of lacking special tools or ignorance or both. I say that with proper maintenance and care, an electric shift will outlast a manual shift dog and gear and associated linkages. Neither one is suitable for use as a rock crusher.

Re: Super Seahorse V 75

Ye but F R if its been sitten a while the selionds can go or if water got in freeze em up. No one wants to work on them cause they were a real pain. Also my personal opinion is i like to be able to push the shifter and hear it clunk into gear instead of relianing on a little seliond to half asssly push it into gear. If they were so good and could "outlast " any manual shift wouldnt they still have them today? Also i stick by my statement that the old Johnsons where a real slouch on power.

Re: Super Seahorse V 75

Not to argue, but I said something about properly maintained. If full of water, it can do serious damage to either system. I also mentioned expensive. The V4-75 in question did not have solenoids. Hearing a clunk as it goes in gear may feel good to the ears, but it can also go halfway into gear through sloppy linkages and still clunk, so that doesn't mean a lot. I stand by what I said about why people won't work on them. I have personally had many dozens of them apart, both electric and manual. The electric requires special tools, but other than that there is not a real big difference in ease. They both can be a real pain or even impossible if they have been in salt water, which is where I live. Power? Yes, I'll agree on that. But most of that is attributable to the lower unit design. When they went to the thru-hub-exhaust gearcase performance was greatly improved. Why did they quit making the 75hp electric shift lower units? Simple-they went to the thru-hub style which was much better. OK, so before somebody points it out, electrical failure could leave you stranded which could be another reason. Just my opinion and observations after many years repairing them every day.

So over all the electric shift really sucked. You really stated that your self.

Re: Super Seahorse V 75

His original question was whether they are good or bad motors. That sort of invites opinions. Unfortunatly, it seems like it results in arguements though.

Re: Super Seahorse V 75

No, I didnt want to "Argue" Im just pointing out that the electric shift wasnt the best setup for the old johnsons. He asked if it was a good or bad motor and I gave him my opinion on it and I strongly agreed it was NOT a very good motor because of the electric shift and the over rated Horsepower. I dont have a problem helping him out if he askes a question Im just telling him why alot of people dont like the older Johnsons

Re: Super Seahorse V 75

Hmmmm, haven't heard from Freddy since that first post. Before I enter another reply, I'd want to hear back from him with the model number of the engine so that we know what we're speaking of.

However, pertaining to opinions and not facts, someone once said that that opinions are like a certain part of ones anatomy....... everybody has one, and it usually stinks (grin).

Re: Super Seahorse V 75

Well the good news. I picked it up today boat, motor and trailer. In checking the model number I find it is a 1960 75 hp Johnson. It is not an electric shift but a manual shift and appears to be very clean. I bought boat motor and trailer for the motor only to fix and sell, but it appears I may have already traded it pending a compression check on it. The guy that took the boat and I are fairly well convinced that it is the original motor that came with the boat. The boat we believe is a 60 Landau by Owens. http://www.fiberglassics.com/owens/owens002.jpg
The trailer also appears to be of the same vintage. He has a 40 hp ? Lark of the same vintage I may be trading for. We will see.

Re: Super Seahorse V 75

Joe the serial number on it tells me it is a 60 model. It appears clean. I haven't done the compression check on it yet, but I did pull the rope and it's not locked up. I also shifted it in forward and reverse and it locked the prop in both. From the trailer plate that was on the boat it appears it has been in storage since 1982 outside. I'll have to get a manual and tear into it. If it's got good compression I will probably trade it to the guy who is taking the boat.

Re: Super Seahorse V 75

it's definately an Owen's, and I think it matches the Landau shown on the link. I'll let you guys know about the compression check once I get it done.

Re: Super Seahorse V 75 compression numbers

Re: Super Seahorse V 75 compression numbers

With a screw in compression tester we got right at 90lbs of compression give or take a pound or two on all four cylinder just using the pull rope four times. . funny thing we pulled the plugs and all four plugs were brand new never fired. Wonder if someone tried to get it going before selling it. to me. I do have a question. I checked for spark and didn't have any. Am I correct in saying you need a battery hooked to it on this motor to get a spark?

No, the 1960 was magneto ignition. No battery needed except to electric start it.
