Re: Motor Wont Start

Howdy, The size and the alpha drive is a good start but could also use the year of the engine and if it is carb or EFI. The engine serial number is best. Could also use what it is actually doing, cranks but won't fire, won't crank (turnover), etc.

To start off with I would suggest going to the top of this section in the Adults Only section and look at number 6 first and if need be number 8. There is also a Mercruiser section for a lot more info on what if's and links to service manuals.

Re: Motor Wont Start

K, your other thread said you needed a water pump? Outdrive water pump or engine? Also, if temps are in the 20's at night as you said in other post, if your boat is outside, you need to be sure the water is out of your engine and manifold. You should also drain the outdrive of oil in case any water in outdrive. If the oil is clean, without any milky looking residue, refill with Mercruiser high performance gear lube. As mentioned, go to the adults only section of this forum and read about mercruiser, winterizing etc.

Also, look in Adult only section for where to find the engine serial number and drive serial number and post it. If you try and start engine without water to outdrive if your impeller is not bad now, it will be!

Once we have your numbers we can help with start problem.

Your transom serial number "0C382348" is the outdrive drive serial number. Could still use the engine S/N unless the other number you listed is the one taken from the starter. If this is the case you may have a repower.

A trace of water may be found if that, but that should be about all

The first number i got off the right side rear of the motor and the second i got off the upper unit of the outdrive.

Re: Motor Wont Start

Please pull the drain plugs like Bondo said! At least for the sake of us out here in forum land

Re: Motor Wont Start

yes, if the engine was run on muffs, or a garden hose right into the intake hose, it has water in the block, and manifolds......if it was run briefly without water, there will be little. as above^.......pull the plugs!

Re: Motor Wont Start

alright ill do that today when i find them..... also the motor wont turn over but i will crank so ik its not seized.

 

[jcbache]

Re: Motor Wont Start

Might as well get this out of the way... cranking and turning over are the same thing> turn the key and the starter makes the engine spin. Firing, hitting, almost starting, starting , running, etcc is when the engine actually has something ( hopefully a fuel/air mixture) igniting in the cylinders.

Nope,... My guess is it's a GM castin' number,....
