I have been working on my 82' model 9.2 A and need some input on the following issues, please. The boat is now in a slip. This boat had been sitting close to 2 years when I purchased it from the PO. I have managed to tackle most all of the issues but still have some questions.
1. The engine is a Yanmar 2GM. The PO stated the engine will only start if the throttle is wide open. He had owned it for the last 21 years and stated to me it's always been that way. It fires right up and as soon as it starts to run, moving the throttle to the idle position works really well, typically not going over 1300 to 1500 rpm and it runs stable at 1000 rpm as it warms up. After it warms up it runs really well IMO moving the boat along at 4 to 5 knots at just around 2000 RPMs. I asked the maintenance department about it and they stated they had never seen this before and suggested leaving it alone if it works well. I was wondering if anyone else had a similar issue or some knowledge to share.
2. The glued-on carpet in the head on the ceiling and side wall where the Beckson window is, looking for suggestions as to what would be a good replacement for that material that is not carpet.
3. This boat has always been a fresh water boat if that matters regarding issues with water tank. I had been reading about the issues of the fresh water tank located in the v-berth regarding pitting and corrosion. I removed the v-berth cushions as well as the removable board just above the tank. All I could see at this point was the wood covering the tank, a one-inch round hole in the wood where the vent line was. I removed the vent and used a bore scope to inspect but was not able to see the entire inside of the tank. The tank looked clean with no signs of pitting or corrosion, just some white brittle scale here and there. There was no foul odor and the very small amount of water inside was not discolored. What is the best way to get rid of this scale so I am not fighting clogged lines to the pump and after the pump? Additionally, the next day when I returned, I had previously removed the carpet from the cabin sole to the v-berth a week before so the fiberglass floor was exposed and there was a small amount of water on the floor right at the v-berth. My additional questions are... where is the water picked up from the tank by the pump? At the bottom or side of tank down low or is the connection up high with a standpipe inside the tank? If it is a standpipe then I must have a leak at one of the seams and if not a standpipe, my guess would then be at the connection down low on either the aft or side of the tank. How is the tank attached to the boat? Is it fiberglassed in or just shaped to fit and sitting there in a box made to fit? Last question. For those of you that have removed the wood just above the tank, what did you use to cut it out with? It appears there is little to no clearance between the wood and the top of the tank.
Thanks
