Twatsoo 60hp won't fire up

Was at the stage of mounting my 2006 Twatsoo 2-stroke engine onto the Ribcraft 4.8m to progress the build. Wanted to adjust the trim/tilt, but all I get is a 'clicking' sound. The battery has a good charge, all cables connected properly. I keep thinking it must be an in-line fuse, as the engine won't start either? Just turns over but fails to fire. Plugs are fine, fresh fuel, etc.

Would it be a solenoid, or is there another in-line fuse we missed?

Any help greatly appreciated.

The clicking sound will be the relay energising, so you're getting power from the trim swich to the relay, but if that's all then theres no power from the battery to the trim pump motor.

Are you getting a spark when the motor turns on the starter?

Have you got a spark? Is the choke on? Press the key up before firing her up. If you dont hear a "click" the choke solenoid isn't energising. It could be helpfull to syrenge a little fuel directly into the cylinders via the spark plug holes.

Thanks for the tips folks.

Looks like we may have missed the choke. Just double-checked the manual online. I see the key needs to be pressed in for choke. For how long though, until start-up, then simply release?

Still have a query with the trim and tilt. Surely this will operate, irrespective of whether the engine is running? When it was first connected to the battery, I adjusted the trim on the engine itself (not the control unit) and it dropped half and inch. Now all I get is a click when trying to activate trim. Surely this is a broken wire or connection somewhere?

This engine had been mounted on a stand for over 10 months. Prior to that it was running, and we disconnected the fuel supply and ran her dry (fuel that is). I will swap fuel tanks and top up with fresh fuel for piece of mind.

Will revisit this again next weekend, as it's a two-man job to manoeuvre the engine into position ready for mounting on the transom. Reluctant to mount the engine until the trim and tilt issue is fixed, as I don't want to manually adjust the trim, just to get it back into the garage.

Happy days, was smelling of petrol and 2-stroke oil again. Come to daddy!

Yes Keep the key pushed up until she fires, and give her plenty of throtle also.

I assume everything wiring wise is new?

If your main switch is old, there's a high chance it;s corroded, so when you use anything heavy duy,, I wonlt bore you with Ohms law, but the voltage goes to the swirch rather then where it;s supposed to be.

I got that with my old Suz 25. Solenoid went click, starter hardly so much as hummed. One new switch, all was well.

Having said that, I'd expect both starter & PT to die about the same time if that were the case. Might be dodgy set of contacts i nthe PT solenoid / relay. (or your PT motor draws more than the starter)

I'd look for an inline fuse first.

Quick update.

Checked the engine again tonight. Hooked up the remote control (checked all the wiring) and it seems fine. It still clicks when using the trim/tilt function on the remote or using the switch on the side of the engine.

Didn't bother trying to start the engine as I've removed the thermostat to clean it and will need a new gasket.

The only inline fuse I can see is intact. I removed it, used an emery board and cleaned the contacts, reinserted, but it still clicks. The clicking noise is coming from the PTT relay pictured.

Is the relay goosed, poor current to it, or insufficient voltage? Had the battery checked recently and it was 85% or 12.3 volts. Life in the old girl yet?

There's enough voltage there to work the PTT.

Is the 'up' relay clicking, but no movement also?

Do you have power to the large Red cable on the relay(s)? The other end of this connects to the main +ve feed from the battery on the starter solenoid.

I'll check again tonight. I'm tempted to remove both relays, clean up terminals and reinstall. Had a look last night and it's nice and clean. There's a plastic cover over the electrics and it feels as though it's been sprayed with Quicksilver Corrosion Guard or WD40 at some point.

How do I go about testing if there's power from the main live feed (red cable)? I assume you mean from the relays themselves.

Can't see whay the relays would be faulty? It was working sweet as a nut before it was laid up for 10 months. PTT wasn't an issue before.
