   Ah, ok, I think you mean T6.354, Turbo, 6 cylinder, 354 cubic inches, about 5.9 ltr, 145 hp, I was guessing they might be. 

I have been running a pair of these for the last 8 years.

Are they hunting under load? One peculiarity of these is that when the injection pump cant get enough fuel the revs appear to rise, then fall back then rise.  Its something to do with the level of fuel in the injection pump affecting the govenor.

I'd guess that maybe they dont exhibit this when not under load, right up to max revs?

Next time she's doing it, look very carefully at the bleed off that is mounted on top of no.6 injector, hopefully its a clear nylon fuel line, check for bubbles travelling along the line, its a sure sign that the injection pump is not getting enough fuel.

How long since the filters on the engine up top next to the header tank and the pre filters were last changed?  I'd reccomend changing the filters as a complete set prior to fitting a lift pump.

	Garth Thank you Sir, I shall be at Sandwich tomorrow and will convey your message word for word to our Skipper Mr. Peter Lash who will then carry out the test you suggest. For your information, the vessel has covered about six or seven hundred sea miles since I checked or changed the filters. I will do my best to locate a Napier Sea Lion for you, J.Cook

	RASC Garth Thank you again Sir, Following your lead, a local mechanic removed the Lift Pump and found that one of the valves of this apparatus was dislodged from its place, this was put right and the engine runs very nicely again. Activity seems to bring its own reward! This evening readers of our website passed the Ten Thousand mark, www.coastalmotorboat.org There is still time to come to our little party by the boat, 7pm August Bank Holiday MONDAY, the Quay, Sandwich Kent. John Cook phone 07907 895281

	8am today Garth (34), passing Margate on a heading for Canvey Island and home. Skipper today; Peter Lash, the Quay Master at Sandwich with engineman Jerry. So after more than four months at sea and journying some six hundred miles, we return to our mooring and clubhouse at the Smallgains Marina. To all of those thousands of visitors who spoke to us and to the hundreds of children who "fired" our Lewis Guns: one leaky tired old boat says thank you. Next year, with a full order book already, we may need to increase our time away to five or six months. And from this tired leaky old man, goodbye 'till next year. J.Cook ps we will have our Vickers mark 8 single barrel pom pom lowered onto our fordeck and ready for the thousands in 2011
