Re: How do you hot-start a sailboat engine

I think the best advice is to get a new ign. switch, the old switch should be marked, if not should be able to download wiring diagram

Re: How do you hot-start a sailboat engine

Eventually you will have to replace the ignition switch. Doing it now leaves less room for oopsies.

It was quite common for small engine suppliers to offer their motors without the wiring loom as a cheaper option. And as a result installing the motor would include making up a starting system, wiring gauges and warning lights etc.
That brings back memories. Pops boats had a key ignition switch just for show. All it took was turning a switch and pushing a hidden starter button.

Re: How do you hot-start a sailboat engine

On some marine engines the key is somewhat of a dummy. Try (gently) using a screwdriver to turn the ignition. Sounds crazy, but I've seen this when viewing boats.

Also, changing the key cylinder should not be difficult.

Re: How do you hot-start a sailboat engine

RR,

Would you be interested in a scan copy of the Owners Manual for a 1978 2-27, Hull #550? If I recall, the engine section addresses both gas and diesel versions.

If so send a PM.

We have have changed the oil, points, plugs etc but not sure how to start it without a key. We can get to the ignition from the back.

Any advice on how to start it would be appreciated, thanks.

I bet that key turns up as soon as a new one is sourced. Murphys Law

Re: How do you hot-start a sailboat engine

I have personally seen two boats explode from sparks in bilge. Also consider installing a second switch in engine room connecting solenoid relay. Nice to have a secondary since ignition switches go bad all the time. Be careful.

Last I heard the art of hot wiring has changed. The new ignition systems are easier to defeat. Like many things, more brute force and less skill.

He will need to find someone who grew up in NYC in the 60's..... Or so I heard

Or someone who grew up in the Country, a 73 Ford pickup had a plug that plugged into the back of the ignition switch, just reach under and un-plug it, no reason to get under the dash. Jumper the ignition wires and momentarily jumper the starter wires

Some of the older cars, maybe from the 60's (you know, the ones without seat belts ) had ignition switches that didn't need keys, you could turn the switch off and remove the key and use it without the key, switch had "wings" like a wing nut, but to "lock" the switch, you had to turn it further, then remove the key. Most people in the Country had lost their car keys sometimes in the past.
Average small aircraft like a Cessna, there are only about ten different keys, most mechanics have a few keys that will fit almost any aircraft on the flight line.
I guess "back in the day" we weren't nearly as security conscious?

Re: How do you hot-start a sailboat engine

I think I'd install two switches, one toggle that powered the ignition and the blower, and one momentary that powers the stater relay. Leaving the ignition on for a couple of minutes while the blower runs won't hurt anything I don't think.

Re: How do you hot-start a sailboat engine

Nobody mentioned it specifically
So here goes
You need a BLOWER turned on for at least one minute before
even attempting a start
Screw driver shorting the ignition
Gas fumes in bilge
Boom goes the Boat

I'd "BLOW" for at least 5 minutes...10 would be better. And open some hatches and bilge covers, and check with your nose. And don't forget to put it in neutral. And as soon as it starts, check for cooling water over the stern, check the volts for charging, and check the shaft at the packing gland for leaks, then stare at the engine a while to watch for drips, oil, fuel, water, etc.

Who says sailing isn't glamorous?

But the first thing to do is...start the video camera...we want to see what happens.

Love it! I grew up on smudge pots. Opening the hatches and the blower on was a given.

Remember the good ole days when all you needed to start your car was the tinfoil from a pack of cigs
