    Hot water heater

    I am in agreement with Grub and he has a good point. The blue tubing is cold water feed. The red tubing is hot water out. The valve on the cold water side is utilized to divert the cold water feed and not allow it to enter the heater. While in the normal position, hot water exiting the...

    Hot water heater

    If you do not have a check valve in the cold water feed to the heater, and it appears that you do not, I suggest that you install one and see if that resolves the issue. It should be before the cross-over to the hot water side of the heater. If you do not taste or smell coolant in the "hot"...

    Hot water heater

    Another issue: it does not appear that the "winterizing" system is properly plumbed, if in fact it is utilized for winterizing. You need a second diverter valve on the hot water side of the "T" to prevent the antifreeze from flowing back into the heater. The process would be to close both...

    Hot water heater

    Something does not make sense. The closed loop engine system circulates coolant. The water heater is tapped into that system. If there is a leak in the water heater's internal heat exchanger, it would be coolant from the loop into the fresh water system inside the water heater. You would be...

    Need help

    Apparently, he did not. That long round rod is part of the depth sounder transducer. There should be a cable coming out of the rod which runs or used to run to the depth sounder display head. If the cable has been cut off, then leave the transducer alone until you decide to replace the whole...

    Boat reverse polarity

    Have had that problem frequently when stored on the hard for the winter. The problem is in the 110-volt supply line at the marina. You can pick up a line tester and when you plug it in to the outlet, it tells you what lines are reversed or missing. Alternately, it could be your adapter, which...

    blower CFM needed for proper ventilation

    Hose from forward facing vent is for natural flow of air into the engine compartment. It can end anywhere. Aft facing vent should have blower attached to it (really a "sucker") and the hose attached to the suction side of the blower should run to near the bottom of the bilge to remove any...

    Swapping 88' 454 Truck Engine to Replace 93' Mercruiser 454

    No need to change the cam as the truck one is close to the marine. At some point in the production, the Gen Vs started using roller cams, I think and there was change to the coolant passage holes, so the Gen V heads may not be able to be transferred. Have the Mark IV heads rebuilt and the flat...

    Which rear nav light position do I use?

    Actually, the old Chris-Craft IS grandfathered. The current rules require the masthead or steaming light to be at least one meter above the sidelights. The old rule allowed the white forward light (a/k/a masthead) to be below the sidelights, typically on the deck at the bow

    Hot water heater hose question

    The fitting on the right is a pressure relief valve. The previous owner put a "T" fitting on the inlet side (left) and connected the pressure relief valve to that so that if there to too much pressure from overheating the water, it will flow back into the heater and not into the bilge. Don't...

    Uniflite hin

    Uniflite's HIN, if there is one as early ones did not, do not generally indicate a "model". More often than not, there were only one or two models from any hull mold. However, the photo appears to be a hull from the late 1960s. The configuration was simply called a "cruiser" and they made...
