Help with parts on 1967 and 1968 Mercury 35's

[Ginder75]

I recently acquired two Mercury 35's to blend into one working model. The serial numbers are:<br />2489015 and 2258858. Both of these are Models 350's. They are identical (short shaft, electric start, remote steer).<br /><br />I can not get Mercury Parts to recognize these serial numbers. What am I doing wrong?<br /><br />I will be looking for a starter, electric choke selenoid, and an exploded parts diagram.<br /><br />Any tips, or quirks with these 35 hp Twins?<br /><br />Thanks,<br />Ginder75

mercurys website only accepts motors newer than 1980 and up.<br /><br />go to oldmercs.com you just cant beat them, they have everything

I went there first, but I did not see the Electric choke that I need. Any other suggestions?

Quirks - keep an eye on the lower unit oil. Those steel shafts are prone to rusting, particularly under the waterpump base and at the propshaft seal.<br /><br />Also, don't wind them out. Get a prop that keeps RPM maxed at no more than 5000. They can break crankshafts when spun higher.<br /><br />Other than that, they are good, solid motors. I've got two myself - a '67 and '69. <br /><br />Do either of your motors have the electric start flywheel? It'll have a ring of teeth on the outer rim. If so, then a starter isn't too bad to find - same ones used on the 35, 40 and 50hp Mercs. up into the 1980s. As for the choke, you'd need the solenoid, linkage and wiring. Might be easier to find a donor motor with those parts. Due to the first weakness I listed, finding a donor generally isn't too hard once you start poking around marina back rooms and graveyards...<br /><br />- Scott

Both my motors are electric start, but both starters are less than perfect. The best of the two is too weak to turn the motor over with the spark plugs in. But if I take them out, it will turn the motor like crazy.<br /><br />Choke - I had an electric choke on the motor. But the wires have become rotten with age. So I really need the solenoid, I have all the linkage and other parts.<br /><br />Anything else I need to know? What type of compression should I be looking for on these motors?

Can you list a link for that website? That is not one that I am familiar with.<br /><br />Thanks,

You can probably rebuild the starters with OTC parts from a Merc dealer. Sometimes a disassembly, lubing and clean-up is all it takes as some corrosion may be gumming up the works.<br /><br />- Scott

What is the best way to check a solenoid (sp)?<br /><br />It makes an awful loud click, but the starter never moves. If I bypass the solenoid, I can get the starter to lug (slow), but there is movement.<br /><br />I am going to redo the main wires from the batery, through the plug, to the ends.<br /><br />Any other tips on tracking down the slow starter problem.

Hi Ginder,<br /> Simply take the starter apart and make sure it's clean and lubed at the bearings. If the brushes are shot you can usually get new ones, or adapt others to fit fairly easily...<br /> Try swapping the solenoid from the other motor. They either work or they don't. New ones aren't very expensive and should be available at a Merc dealer. Same or similar ones that will work were used up into the 1980s and 1990s...<br />- Scott

Alright, I spent the weekend fishing out of Dad's boat and it is time to get mine back on the water. I was going to give the starter a good going over, but I can't seem to get the starter off the motor. I have removed everything that I thought was in the way, but the bindex will not clear the mounting bracket.<br /><br />Do I need to remove the lower cowl assembly? If so, what is the best way to go about doing this?<br /><br />Final question, I am also looking for Throttle and Shift cables for this motor. The set I was given will not work. Any ideas. I know this is a lot of questions, but the board has always been great in the past.<br /><br />Thanks,

Okay, several hours later I have some conclusions!<br /><br />The starter on this motor was the FIRST part to put on the block and everything was built around it!<br /><br />A weak battery does not help matters when you are chasing down an electrical problem.<br /><br />My hands are too big to work with the LITTLE bolts and there is always a place for you to drop a nut!<br /><br />Actually, the starter has been pulled, cleaned, put back together and tested. I did not get a good test (see above). My battery decided it had all the fun it cared to have in one night (will replace tomorrow).<br /><br />After some homework, I have conculeded I need Teleflex -CC179's to finish this project.<br /><br />I measured from the control box, along the hull to the transom and too the center of the out board. This distance is 10 feet even. I have read three different ways to calculate overall cable length. Do I add 2 feet, 3 feet, or 4 feet to this measurement for my final cable length?<br /><br />Thanks
