Re: Discolored teak trim

I have successfully used Teak Wonder to get rid of dark spots on teak after removing old varnish.

The brightening component in Teak Wonder is a mild bleaching agent.

Or you could use oxalic acid or other bleaches.

Re: Onan 7.5 MDJE problem

Could be the diaphragm in the lift pump is broken. it is easy enough to dismount and take apart the pump to inspect.

You might first try to rotate the crankshaft a bit, either manually or with the starter, as in some positions the manual pump lever does not work.

Re: Price for Teak Removal and Paint Decks GB42

I have used the Feinmaster to trim-off the excel caulk and this method worked well. If you don't have a Feinmaster you can use Bob Lowe's bent chisel approach which has also worked well for me. The chisel is easy to bend when held in an anvil. make sure it is very sharp and simply push along, flat o...

Re: Higher temperature in port engine

As mentioned below, bits of old impellers can get stuck in the most improbable places and reduce the raw water flow. I am not familiar with the Cummins engine but on my Onan generator I found several rubber vanes in an elbow right after the pump that had probably been there for years. When I cleared...

Re: Transmition Cooler Descale

I would guess it is calcium carbonate and other carbonates precipitating out of the sea water, same as what happens in domestic water systems in "hard water" areas.

Re: Higher temperature in port engine

You may want to confirm the temperature sensor and gauges are working correctly by comparing the engine temperature when measured with an infrared thermometer. But, as Berger suggests, the heat exchangers are a the usual suspects here. Have these ever been replaced or cleaned out? You can take off t...

Re: Interior water condensation or leak?

My previous boat was a GB 1979 Classic and I had a leak in that area. It was caused by deck screws that had been reset deeper and had broken through the fibre glass under-deck.

Re: Rocna Anchor - GB42 Classic

According to the Lewmar Delta chart, 25 kg should be plenty for your 42'. I think the Delta is not a bad anchor but, nonetheless, I prefer a new generation anchor such as Spade or Rocna as I believe they are more likely to re-set after a wind-shift in the middle of the night. The windlass should hav...

Re: Haul Out Grand Banks 42 Classic

I have never seen "cushions" being used nor think they would serve for anything.

Side forces from the sling would not be large and the bulkhead area would be very solid.

Re: Spade 140 or 160 on a GB42

I have an 88 lb. Rocna which works well in my GB50. Were I richer I would have bought the next size up (121 lbs.)

According to the Spade Anchor guide, for your boat the Spade 100 seems already oversize, which is no bad thing.

Re: Anchor Type

The Spade is reputed to be an excellent anchor. More expensive than the Rocna but no rollbar.
