April 14, 2024 at 6:50 am I think I’m missing something. For years I was able to search the forum. over the last several months the search function in the forum only returns parts selections. Ive tried logging in on different computers and with the following search engines, Safari, Chrome and google. No luck. Is there a setting im missing any ideas on how to get the forum search function to work? All other aspects of the site work. This post will be a test as to wh…

QSB 5.9 Coolant drain and fill

6 hours ago April 27, 2024 at 1:40 pm Hello guys, I will be draining and replacing coolant on my 2005 Mainship for my first time. Ā In reviewing your technical info, you show a drain plug at the red arrow, but mine does not have a plug there. Ā I do see a plug at the other end of this tube, as shown in my photos where my finger is pointing (the next is the close up one is from underneath the tube).

Impeller puller for Sherwood 1730 raw water pump

May 1, 2024 at 7:01 am Does anyone have experience with an impeller puller tool that works with a Sherwood 1730 raw water pump?. this is on a 6BTA engine. Amazon has one from Jabsco but I would like to know if it (or some o0ther tool) would work. Thanks

1 ReplyMay 1, 2024 at 4:29 pm That depends. If your impeller has threads in the center, get the tool that screws into it and pushes the impeller out. If not, remove the plate, bump the engine over and hope it will allow the impeller to come out a bit. A tapered vice grip helps pull it out. The last one I did for a friend took 45 minutes pulling alternate sides with a vice grip.ĀLast Post by:

April 26, 2024 at 7:08 am First time I noticed this was after putting the boat back in the water yesterday and going for a long ride to test temps out after servicing the Aftercoolers per Tony’s method. Ā There was oil ontop of the transmission which seems to be coming from the Turbo. The oil is clean and looks new so it must be from my recent oil change which is why I believe this is a new thing that happened yesterday.Ā Ā Ā

April 18, 2022 at 8:11 am After the thorough information and write-ups from Tony and the SBMar team, and the readily available parts kits they supply, I decided to tackle my aftercoolers this year. This is my second year with this vessel, a 2001 Tiara 3800 Open with 6CTAās, roughly 500 hours. It was previously serviced by Gorham Diesel out of the Boston area. The aftercoolers were replaced with brand new ones 4 years ago, so I am assuming that this is the first āserviceā…
