    8.1 GXI-J Cranks but No Start w/ Diacom Logs

    IMO - it is not worth chasing possible causes. You are probably going to have a new engine (at least a new long block) and can start fresh. Usually, the center & rear cylinders get the water from a leaky exhaust. IIRC, the headbolt that snapped was at the front of the engine. Hydrolock...

    7.5 Merc. Cooling system issues? What is this tube?

    I am not sure if there is a t-stat on these engines, but mine is 10 years older than your 1979 model.

    7.5 Merc. Cooling system issues? What is this tube?

    I was not sure what that was, but I do not see that on any parts diagram for the motor. That passageway feeds water to the exhaust (not the only water feeds to the exhaust - there are more). So, that 'tube' . . . probably not supposed to be there.

    Hydra-sports question

    Here is a picture of a 1990 Hydra-Sport transom rebuild. So, we know the transom is wood core. Probably the rest of it is the same. You can Google some restoration threads of that era for more pics, etc. . . One thing to check about the Hydra-Sports is the fuel tank to see if it is secured...

    7.5 Merc. Cooling system issues? What is this tube?

    The copper tube feeds the water from the water pump to the powerhead. There should be a phenolic washer where the arrow points. Maybe it came up with the powerhead, check to see if it is there. Also be sure the water pump has the larger plastic tube that mates with the copper tube during...

    New Boat Launch Ramp

    Our local boat launch ramp is getting replaced. It seems like they are re-grading it to make it steeper by the looks of it. The stones are placed over the existing ramp. I'm not sure on the construction method so far; it appears that more than stones will be needed to re-grade . . . perhaps...

    Quit My Job . . .

    New Tires . . . $1,000 Alternator replacement . . . $1,000 Brake job . . . $600 etc. Often comes up to $300/month, but never any consistency, so the money does not get allocated.

    Quit My Job . . .

    The Admiral has the steady income of the household. Mine is here and there. She does a monthly budget, but tends to underestimate or not include all of the costs (things like . . . auto maintenance, house maintenance, boat maintenance, etc.), so there is a constant 'dream' vs 'reality' going on.

    Winterizing questions

    First Pic . . . Sea water pump and sea water strainer. Water comes from the outdrive (or a thru-hull fitting) and goes to the sea water strainer first (where marine life/debris is captured) then onto the sea water pump. Third picture . . . that is a flush adapter. It allows you to get water...

    8.1 GXI-J Cranks but No Start w/ Diacom Logs

    No . . . usually it is the exhaust riser gaskets.

    Those with MPIs what do you do with your leftover storage gas mix?

    I have the 6.2L versions, similar to the new 4.5L. The fogging mix is about 10:1 as specified in the manual, IIRC. Since I don't like disconnecting the fuel line to run the fogging mix from an Aux tank, I empty the main fuel tank and add about 5-10 gallons of the 10:1 fogging mix then run the...

    . . . and I Thought Hi-tech Boat Engines Were Bad . . .

    I like some of the tech, be it on cars or boats, but it seems like it is less than bullet-proof.

    . . . and I Thought Hi-tech Boat Engines Were Bad . . .

    Yes, using the existing profile. If I get a new battery, I'll have to register it to the car computer as 'new'.

    Most stable hull design for trolling in rough water

    There may not be any good solution to the issue you described. Would you really go out and buy a different boat just to resolve a tipping issue? Decent sized wakes against the side of the boat is definitely going to be a rocky ride. Wider beam can help, but maybe not all that much. The whole...

    1993 Baja 24 outlaw stringer question

    Also, as you join the wood pieces of the structure together, put a layer of fiberglass in between where the pieces meet. This prevents moisture migration through the structure.

    1993 Baja 24 outlaw stringer question

    Use polyester resin . . . epoxy and PL are not going to be compatible with the resin you are using for the re-build. If you want to make the stringers wicked strong (and rot-resistant) put a layer of 1708 cloth along with the resin in between the 3 layers of plywood
