My engine won't start

[Jon H]

I decided to winterise my Evinrude 70 today (about 8 years old)

Big problem, engine wont start and neither will the tilt for engine.

The battery is fully charged but when I try to lift the engine or start it I just hear a high pitched, high frequency buzzing from the engine.

Upon investigation the buzzing was coming from two , what look like, relays under the engine cover.

The starter just won't function at all.

The inside of the engine cover was really wet (beads of liquid on the sponge sound proofing).

Any ideas anyone ?

The engine can be turned by hand so it is definitaly not seized

My guess is that its all "damped out"

check that the full voltage is getting to the engine, check earth on block, if you have jump lead try putting them on the starter relay and earth and then touch the small wire on the same relay with the live, if it turns over then its either battery leads or main loom plug, whatever it is it sound like electrics related, i've also seen corrosion in the battery switch and batteries that show full charge but not man enough to turn an engine over

It'll be a bad contact. Either the battery clamp,battery switch or one of the crimped terminals on the main battery cable.

I am a bit wary of messing thinks up even more than they are so I guess I better find a competent service place in Northampton area to sort it out

pull the loom plugs apart and put them back together and look for crud around battery leads first, might save you a couple of bob
