About three weeks ago I finally got my boat in the water on the boat yards cradle.
I was taken out to it just as it floated free and just in time for quite a wind to blow up which need several persons to hold it away from the steel cradle as I reversed out.
As a result I had no time to run up the engine before setting off.
I turned on the ignition,gave it 20 seconds heat noting the voltmeter needle dropping as I did and fired the engine.
A repeated cough but no start and I already suspected the cold start but there were two yard staff waiting for me to go so I switched in all three batteries and finally it started.
I then reversed out of the cradle and headed of out of Loch Kishorn towards Loch Carron into to the teeth of very gusty winds and by now quite a swell. I had just cleared the old oil rig yard as I noticed the temperature guage heading for boiling point! I returned with difficulty to the cradle,allowed the engine to cool and checked the indirect header tank-empty.
I filled it up and started the warm engine no problem and took the boat across to my new mooring at Plockton.
In hindsight I realised that when I drained the engine block in the autumn and refilled with antifreeze it had airlocked which is quite a common problem and as during the winter I had only briefly run the engine on several occasions the airlock had not had the opportunity to clear.
(I once did this on my Nissan Terrano and it cost me a new cylinder head!)
As for the starting problem I had during the winter had the heater plugs out to check their operation and when I tested for continuity found I had at best just two working as I hadnt tightened up the knurled power lead nut properly connecting number two to number three and persay number 4 heater. Unfortunately its in a very arkward place behind the inlet manifold.
Solved this issue today in very hot and humid conditions.
