A Phosphoric Acid solution worked well for me in flushing the raw water systems for the Detroits, generator and AC. Engine operating temperature dropped roughly 30 degrees and sea water flow through the generator doubled. I had concerns regarding acid concentration and checked the MSDS for...

After flushing the engines raw water system I started replacing the engine zincs. I noticed there were brass plugs just below were the raw water lines enter and exit on each end of the 1983 Detroit 671 TI intercoolers .. The plugs looked like the smaller engine zinc plugs so I undertook to...

Lilly Marie developed an overheat issue a few weeks ago. The starboard engine usually goes no higher than 165 degrees however it got up to 185. I assumed the impeller needed replacement; but when I pulled it, there was no apparent damage. Since its been probably 6 years since I flushed the raw...

My old Garmin radar quit working and I've decided to replace it with a solid state Fantom and trying to decide if the extra 6 inches is worth the additional $800.l I don't care about finding birds, just collision avoidance in reduced visibility. Shared experience will be appreciated. Thanks

I putting together a 24v battery bank of Golf Cart Batteries for a trolling motor. Any thoughts regarding the use in series of (3) 8volt batteries vs (2) 12 volt batteries. I have sufficient space for either option.

My nephew is looking at buying a mid 1990s Cabo with 435 hp Cats 2500+ hours. He asked what his Hatteras owning uncle thought about the boat. I said I’d check. Insight appreciated. Thanks

After several weeks of not going aboard I noticed a strong diesel smell in the saloon. A check of the ER revealed some diesel below the deck between the engines. Stated removal with a hand transfer pump, graduated to using a shop vac. Probably took out 4 gallons of fuel. Started looking for...

After 39 years the flange which connects to exhaust housing for the turbo charger on the stbd 671ti broke off. Will need to replace the housing or perhaps replacing the whole turbo might work. Any suggestions re sources for parts. Considering the boat's age and mine, used parts might make sense.

While running the engines at the dock I notices large bubbles coming out from under the port side of the boat every few seconds. This is located approximately 2 feet aft of the aft engine room bulkhead and only appear on the port side of the boat. Since I first noticed this, it occurs every time...

2013 I installed an inverter system on Lilly Marie. Overall I have been well pleased. The Magnum 2800 MS system has worked well, was used often and saved unnecessary generator use. The 4 lead acid 6v batteries from Sams Club lasted Over 7 years. Replacing the 65# batteries, struggling to...

I've been well pleased with my Magnum 2812 Inverter with 4 6v golf cart batteries in series/parallel. However, I am tired of the port list created by my placing the battery bank and inverter on the port side of the port engine. It occurred to me that I might move the inverter batteries to the...

I hauled out 2 months ago to address the port shaft which was much harder to turn than the stbd shaft. Before the haul out, one person who studied my problem said the motor mounts were bad and should be replaced. A second opinion concluded the shaft was bent. The only thing I was convinced of...

The most difficult part of removing the coupling was the cotter pin. The hole in the coupling was about 3/8" aft of the pin. With the PSS shaft seal, the shaft does not go back very far and to see the cotter pin very well I had to use a mirror to see what I was doing. Retrieving the pin was...

Removing paint around the threads sounds like a good approach. I removed the strainer baskets leaving only the frame. That allowed me to pass a 30" length of pipe thru the frame and get significant leverage. A pipe wrench was necessary to hold the lowers section in place. I have the...

Its been over a year since I installed external sea strainers. They have worked fine and I'm now committed to remove the internal strainers. The drip-less shaft seals are at least 11 years old and the manufacturer advises replacing the bellows every 6 years. Lilly Marie is hauled out and I've...

I checked the site to verify maintenance information on Lilly Marie's 10200 Capitol Gears. If its here I couldn't find it, but did find a web site with Capitol gear manuals http://capitolmarinegear.com/manuals-part-lists BTW it recommends 30wt oil, I've been using 40 as used in the Detroits

I used sheets of plexiglass to create an aft deck enclosure for our 43DC and have been pleased with the results. If you are interested I can provide more information.

The port helm gear cable broke so I've undertaken to replace the gear cables for the helm and FB. I found the measurements for the FB cables (28 and 32 ft.); however, I notice that there are large loops of extra cable. Over 6' extra cable for the port gear shifter and 8' extra for the STB...

The wire brush grinder revealed #2 square drive screws. I used a small drill bit to clean out the paint then tapped the drive into the hole. 10 of the 12 screws came out easily. The drive stripped on two and hopefully a screw extractor out will take care of that. The screen that is off...
