At 1/4" NPT and BSP threads are only 1 TPI (threads per inch) different so its very difficult to tell what you have unless you have an accurate thread gauge. The angles of the threads are also

I would appreciate the information also Kent, as I am sure everyone would. Look forward to your post ! Cheers Alan Elyse SM437

Hi Kent, It would be good to get those part numbers and sources posted. I've wondered about them in case we need to replace a temp or oil pressure sensor. Bob, KAIMI SM 429 Monastir, Tunisia

Mark, You are correct, I wss wrong. I should have looked at my book. It is 1/4" pipe. Best, CW Bill Rouse Admiral, Texas Navy Commander Emeritus Amel School www.amelschool.com 720 Winnie

Pat/Bill, FYI, the Burkert gas solenoid on my SM has G1/4 threads. The best I can tell, G1/4 is the same as 1/4 British Standard Pipe (1/4 BSP). It appears that Burkert solenoids sold in the US

Hi again Bill, two more things. I contacted Amel for advice and they told me not to go for the higher hp 110 hp motor as the c drive was not designed for that power and it would fail. Later models

Hello Everyone. No one asked me but that never seems to stop me... A. Dry major consideration when repowering is to be sure and get a diesel that has an isolated negative electrical system. Also

Mark, Reading your reply, I realized that I left out an important fact ,that my engine is a Volvo TMD22a . So my exchanger may be different from yours. I suspect it is, I see no where ,where a O ring

Hi Pat, It sounds asthough you are on the right track. The ends shouldbe sealed with a rubber o-ring. Depending on the engine type there aresometimes 2 o-rings. There should not be silicone.

We have also put some Raymarine instruments in the past 2 or 3 years. You only asked two questions, but I may drone on and give you more answers; I can only hope that at least two of them are

Hi Bill, we replaced the TMD 22 with the Volvo D2 75. We retained the same Hurth (ZF) gearbox and it was a perfect fit. The engine mounts were in exactly the same place so bolted to the Amel rail

One more thing about the Yanmar 4JH4HTE... When talking to Yanmar in Ft Lauderdale, and New Jersey(?) I couldn’t find anyone who had a clue about a “floating” ground like Amel uses. Temp and

Bill , I assumed the thread would be metric,Thanks for the info. Pat SM#123

Hi Bill, I repowered 4 1/2 years ago replaced Volvo TMD22 78 HP with Yanmar 4JH4HTE 110HP (the 4JH3 100HP was replaced by the 4JH4). The new engine dropped right in, required new mounting holes in

Ryan, Let me give you the short answer: The AC "Earth" is not part of the Amel Bonding system. The two systems were designed to stand alone. However, when Amel chose the Calpeda 220VAC Saltwater pump

Pat, I believe that all electro-solenoid gas installations on SMs and 54s that I have seen are 3/8" pipe thread with a Burkert 6013 series solenoid valve. See the attached. Best, CW Bill

Ian, Thanks for that! Hope the install goes smoothly and come in below budget! Bill Kinney SM160, Harmonie Solomon’s Is, MD, USA

Thank you very much Bill. @SAV has nothing in stock at the moment. As informed by Amel La Rochelle there is a delay in production. That being the reason I posted this message on the forum. Regards
