April 28, 2022 at 2:23 pm I need some small parts to complete installation of Kobelt controls, and Iām Ā not getting support from my local dealer, so posting here in hopes of finding another source. Have emailed Kobelt directly, no reply. I need a chain kit for a 2091 control head, and two cable ends with pins for 33 cable. Any help is appreciated!
2 RepliesApril 29, 2022 at 5:41 pm Thanks, Clark, I doubled down on the local distributor, and he finally agreed to order the parts. Ā He doesnāt keep any inventory, and doesnāt like to sell small orders, not real kosher, but theyāve got us over a barrel here.Last Post by:

Primer ball with 90 deg fittings
This topic has 3 replies, has 3 voices, and was last updated by
April 22, 2022 at 4:50 am Anyone know where I can find a primer ball like this one from one of the seaboard marine YouTube videos? My bilge isnāt very deep so this would be a perfect setup.Ā
3 RepliesApril 26, 2022 at 10:04 am I wound up plumbing the squeeze ball on extra long tubes so I could move it to a comfortable position to pump it. Ā That eliminated the need for the 90* fittings, and the contortions required to reach it. Ā It hangs on a convenient nearby valve handle.Last Post by:

March 24, 2022 at 1:25 am Hi all, first time poster. After reviewing the great resources on this site about exhaust systems and how they apply to my yacht, one of the pieces of information I have failed to understand is what exactly the anti-siphon bypass is as mentioned below and found on this page https://www.sbmar.com/articles/designing-a-marine-exhaust-system/ Quote: “The general layout of the āanti-siphonā valve.

1 ReplyApril 22, 2022 at 8:15 am A photo or two might help elicit better help.Ā Ā Ā An active bypass as you referred to it is literally a bypass where it has been determined that there is too much raw water exiting through the exhaust system,Ā Ā TO much water can cause higher back pressure than the engine can tolerateĀ for proper performance.Ā Ā Ā This bypass can only be done when it has been determined that adequate cooling water still flows through the exhaust system to keep it…Last Post by:

Multi-Stage filtration for small boat diesel 39hp Yanmar 3Jh5E Diesel

May 6, 2017 at 1:58 pm Hi there. I’ve just bought a sailboat with a new’ish 39hp Yanmar engine and a 20+ yr old tank. With diesel bug apparently becoming more prevalent, I’m looking around at ways of making sure the quality of the fuel getting to the engine is good, and that we avoid clogged filters as much as possible. While researching, I found the Fleetguard Multi-stage “The seaboard way” article hereĀ https://www.sbmar.com/articles/mar…
