Barry's Blog #160 - You should stop worrying

Updated: Dec 12, 2020

"I told ya." said Kev in his usual laid back style "You should stop worrying."

I wasn't worried any more and I was greatly relieved that the first test of A B Sea's engine, after the top end rebuild, had gone smoothly and the engine had worked perfectly.

There are a couple of things which we didn't include in this week's video that raised my stress levels slightly. Before we fired up the engine Kev and I had gone over every hose connection, every nut and bolt and nodded to each other that we both thought we had dotted every i and crossed every t. We'd even remembered to open the seacock valve where the engine sucks in the seawater for cooling.

The big moment had arrived, I turned the ignition key and the engine turned over but didn't fire up. This was planned as we wanted to get some lubricating oil around the engine before it ran normally.

A second twist of the ignition key and after a few seconds the engine roared into life. However it didn't last long before the engine just stopped and wouldn't start again.

Kev went below to investigate. A few seconds later he popped his head out of the companionway. "Did you remember to open the valve for the diesel fuel feed?" A light bulb moment. "Errr no, I thought you had." I replied. A rookie mistake, easily fixed.

A third twist of the ignition key and we were back in business. We let the engine run at tick over speed for a few minutes to make sure that enough oil had been pumped around for maximum lubrication and for the engine temperature to raise slightly.

The next step was to slowly increase the engine revs to 3,000 rpm. As I pushed the throttle lever gently forward a large amount of white smoke billowed from the exhaust. That wasn't part of the plan.

After a few minutes it stopped blowing smoke and we concluded that it may have been the small amount of oil, which I'd injected into the turbo housing as an initial bit of lubrication, burning off.

At 3,000rpm the engine sounded good, there was only cooling water being vigorously spat out of the exhaust and the engine operating temperature was sitting at a steady 60oC. Kev went below to check all around the engine for any leaks and after a minute or so he came up into the cockpit and announced that everything looked fine. A win, we'd done it. We'd successfully stripped the engine, cleaned everything, rebuilt it and installed a new turbo.

What did it cost?

With Aydin, the local engineer, doing all of the coordinating we sourced a new turbo unit from Istanbul and it cost 440 Euros (AU$711).

The gaskets and other small replacement items cost 300 Euros (AU$4
