Hi Chris, I don't know about your specific engine but for my old Yanmar 2QM20 with no glow plug I put the throttle to greater than 1/2, turn it over and she starts. I'll then throttle down to idle put her in forward and give it a nice warm up under load.
To stop it, as advised in the users manual, I throttle down until it stalls then turn off the key to stop the buzzing. I do have a decompression handle but I never use it and I'm able to start in below freezing temperatures; however, I'll often run my diesel heater in the cabin a bit first to warm up the boat before starting in the really cold. Before I knew to put the throttle up so high to start it I burnt out the old starter trying to start on a cold day. After that, I replaced with a new starter and beefed up the wires form the battery to the starter. Now she starts no problem.

When starting we set the throttle to about 1/4 to 1/3 then start cranking. Sometimes I'll engage the compression release to get the engine spinning a little faster (about 10 secs) then release it. Another thing we do is flush the engine with fresh water before putting the boat to bed. Hope this helps. -------- Original message -------- From: Chris Graham via CnC-List <cnc-list@cnc-list.com> Date: 10/22/18 09:38 (GMT-08:00) To: cnc-list@cnc-list.com Cc: Chris Graham <sabre28...@yahoo.com> Subject: Stus-List diesel engine staring procedure I have a quick question about the specifics of starting a Yanmar SB8 single cylinder engine. The previous owner also disconnected the kill switch and turned off the engine with the key so i want to reattach the cable this spring. Is there a specific amount of throttle to set it at prior to turning it over? I think I remember by old Volvo-Penta had to be positioned at 3/4 open and then immediately dropped down to idle once the engine turned over. anything special I need to know? No real information out there and the old service manuals are pretty much impossible to locate at this point. Thanks for your suggestions Chris
