I would look up a Websearch for the brand of motor and the year and engine size. Marine engines have different camshafts and timing is different than on an auto engine. You would look up Mercruiser if it is an inboard/outboard outdrive and has Mercruiser emblems. Same for Volvo or OMC embled outdrives. Ford makes the basic block but the specs go by outdrive makers.

This is because the gearing in the outdrives make a difference in what the engine needs to do.

if you look below the fin on the lower unit you will see some holes on both sides. their is a adaptor you can buy that will cover these holes and it will hook up to your water hose. you can get it at academe or boat supple. jerry

Is the rotor turning? Check your coil and condenser.
The OMC drive system uses Micro switches in the linkage. They switch when the throttle positions are correct. The Micros operate the ignition Module.

Some of the outdrive systems have a starter cutout and some have an ignition cutout for the UP positon of the outdrive. The angle of the outdrive is too severe for the U-joints to move so they fix your boat not to start when the outdrive is UP.

Move your outdrive down and see if the igniton comes back.

Yes, the ignition switch or ignition wires on the Run side of the switch may be bad. Most people don't know that the Start side of the switch can power the spark plugs. But when you stop cranking and let the key go to Run you can lose the spark to the plugs

There is also a safety feature in the OMC system. The micro switches on the linkage have to be adjusted or timed. This is so the throttle is not set too high to engage the outdrive. So it does a lockout of the module or a lockout of the starter.

A second feature prevents starting if the outdrive is up too high. This prevents breaking Ujoints and dangerous planing conditions from an improperly trimmed outdrive. Lower the outdrive.

You will see the microswitches, see if the linkage can be moved to line up the contacts. They are simply contact switches and you may have to temporarily disconnect some linkage to test start.

we had replaced the engine in our 87 4.3 star craft and when we put the omc cobra stern drive back in we now dont have foward gear, we have nuetral and reverse. could it be the linkage or could it be the shifter cable or any other idea's that could be the problem.

I would try a johnson/ evinrude/ bombardier dealer for the diagram. OMC was bought out by them so they should be able to help. However in the marine industry it can be hard any literature on older products b/c they only produce a limited amount of their products.

You can try Bombadier(Spelling?) who bought out OMC. They still make some parts and should know.

If it has a OMC or Volvo most are in the top of the outdrive. If your motor looks like a car engine it can be if the front just like a car. This website claims they have online access to repair manuals so I would look there first. Go to other websites and look for impellers with the brand of motor, like Volvo impellers, Mercruiser impellers and some of those sites have excellent parts diagrams.

There are lockouts in the outdrives. You need to have the outdrive down for the starter to work. There is an operating range on the outdrive to keep the driveshaft from breaking. Be sure to have vent blowers on and water to outdrive or in lake. You don't want to burn up the impeller. Also you need discharge water in exhaust passages or it will destroy rubber parts.
