      March 14, 2024 at 10:11 am Hello, Can someone tell me where I can locate the serial numbers on my Cummins QSB 5.9’s. I need to take a photo for a Temporary Import Permit to Mexico. Thank you, Patrick

      January 11, 2019 at 7:25 pm Hello All, Can anyone tell me if this 2006 5KW generator has a replaceable zinc? Can’t find any obvious sign of one. Thanks.

      January 13, 2019 at 1:55 pm That is a slick set up. Well done. Dan wrote: Patrick wrote: Did you plumb a permanent adapter to hook a garden hose too? Through a tee on the intake side of the raw water strainer (blue valve in picture attached) that is connected to a distribution manifold that both engines, air con, live well pumps, wash down pumps and the generator are fed through a water hookup on deck, I can flush all with the garden hose or the onboard freshwater suppl…

      February 15, 2017 at 4:13 pm I was half way to Catalina on my Tiara when the starboard prop wrapped up a semi submerged heavy duty line. Probably fell off of a commercial vessel.

      April 11, 2017 at 8:01 pm Sea Trial went real well. After having both props balanced and the starboard driveline essentially replaced, the boat runs noticeably smoother with less vibration.

      December 29, 2016 at 6:52 pm Hello all! Great forum you have here. Thought I’d ask if there was any tricks to changing the fluid in my ZF gear box. This is my first time. My understanding is: Warm up first, remove filter cover and filter, suck out old fluid through dip stick hole. Clean filter screen and replace same amount of fluid extracted with new Dextron III ATF. Check levels after brief run Here are some pics of my engine room and running gauge readings on the s…

      December 30, 2016 at 7:32 pm The job was fairly easy after realizing the best suction hose access to the bottom of the gear case is through the filter hole. Ā The gears get in the way trying to snake the hose down the dipstick hole. Thank again. -Patrick
