    Brake Leak

    :welcome: to iBoats . . . . Is the flex line installed something like this? . . Looks like you got to disconnect the line from the surge brake master cylinder, and then from the closest line coupler on the frame in order to pull the flex line out to replace it . . .

    New ladder install

    :welcome: to iBoats . . . It is your boat, you can do what ever you want. :) You mean this swim ladder on the stern ? . . As you can see, the 'cap' of the boat forms the top of the swim deck. So the swim platform was most likely attached to the swim deck prior to the 2 'halves' of the boat...

    Covid-19 Heat Resistance

    Soooo many quasi-facts rolling around you sort of have to wonder if the blood type stats are considering the population of blood types . . . . . However . . . This video may help understand things . . . . Edit: Extremely funny video removed because of the f-bomb

    2016 Tahoe 400ts ice cooler

    :welcome: to iBoats . . . Why do we always have to do the research :) . . . You mean this cooler? Looks like it is an "Igloo Marine" cooler . . . Might be the "Marine Ultra 36 Quart" . . . hard to tell the exact size, but with a tape measure, you can identify the appropriate model/size. .

    Oil Change . . . I goofed up with the ear muffs!!!

    It's launched . . . 25 mph winds and all . . . :rolleyes: Final clean-up last night . . . . . I think harringtondav was interested in the hydraulic trailer that the boat haulers use . . . so there are some pics . . . We usually go a couple of harbors up to launch at a better ramp, then I...

    Oil Change . . . I goofed up with the ear muffs!!!

    Quick Update . . . The boat is all ready for launch . . . scheduled for tomorrow 8AM. Of course the sea conditions are supposed to be a bit dicey . . . early AM should be better than mid-day. I ran the engines one final time, checked for leaks, etc. and also hooked up the computer (Diacom...

    Automotive HP and torque at cruising speeds

    Not entirely boating related, so I am posting this in the non-boating tech section . . . I have always been curious on how much Horsepower and Torque a car generally takes to drive down the road. Folklore has it as 'not that much' as compared to what most engines are capable of. My mid-size...

    Mercruiser 454 timing chain

    When I re-built my 1991 Merc 454, I think the timing chain was a Mehling brand. You should be able to get all of the parts from the engine industry suppliers rather than through Mercruiser. Here is the original Timing set . . . . Here is the replacement set. I got a lot of parts from Summit...

    Red Norox ( MEPK) Vs Clear MEPK ?

    I have used NOROX®MCP-75, ( chemical name Methyl ethyl ketone peroxide/Cumyl hydroperoxide), which is Red vs. the regular clear MEKP. Not sure if that is what you are referring to . . . The MCP is a slower catalyst, so yes working time is increased. I have also used "TBC" inhibitor...

    Clean cuts in hull

    OK, so they are approximately where the arrows point in the picture below, right? . . Do they extend under the windshield frame to the outside area? Those look like big stress cracks. . . Do you know if they stop at the gelcoat, or go into the laminate? That is an unusual place for stress...

    Anode install question

    What Chris said . . . The 'horse shoe' anodes on my Bravo3's don't lay perfectly flat. The important thing is the external tooth washers for electrical continuity. .

    Adding a clear coat ???

    I have been attempting to really clean and shine the hull this year, since it has been getting a bit dull/dirty/stained and has a few docking marks on the hull. I've been using a floor wax stripper liquid to cut through the years of wax and polishing compounds. Also using a scrub pad to get...

    Standard rotation or reverse rotation

    Usually . . . dual prop outdrives do not require a reverse rotation engine with twins. You find a reverse rotation engine with single prop outdrives on twin engine boats, which are usually the go-fast boats. One way you can tell by looking at the propellers . . .

    Overheat 4.3 raw water HELP please

    What Bondo said . . . You may be able to test that theory by slightly clamping off the hoses to the exhaust elbows and see what that does to the engine temperature. Make sure to keep some flow going to the exhaust though . . . The issue could be that most of the new cooling water coming into...

    Oil Change . . . I goofed up with the ear muffs!!!

    Well, I managed to get both water pumps replaced to day . . . took all day though. The second one ( port engine ) was a bit easier than the first one. Of course getting up and down from the boat a million times, I happened to miss the ladder when stepping down to go get another tool. :eek...

    1996 MPI 454 engine block drain plug question

    Usually there is a 1/4" NPT (3/8") reducer and then a 1/8" NPT plug (Items #3 & #4) , but just a 1/4" NPT plug will do in a pinch. Alternatively there is the reducer with the blue plastic plug ( items #5,6,7) I'd get the correct reducer and plug on order though . . . Might be able to get...

    Oil Change . . . I goofed up with the ear muffs!!!

    Here are the remains of the impeller . . . . . That was about 5-10 seconds of running without water supply. I backflushed the inlet system from the heat exchanger on down to the sea water pump and then backflushed the heat exchanger from the discharge to the raw water inlet. Hopefully, I got...

    First time spraying outdrive anti-fouling

    Over the years I have tried all sorts of methods applying the anti-fouling paint to the outdrive(s) of my boat each spring in preparation for the boating season. Brush, rollers, pads, spray can, etc. Of late, the spray cans have been the worst (the valve always seems to fail and the cost of the...

    Time to re-upholster - Formula 330 SS

    I had 'forgotten' to make a new skin for the sunpad filler cushion, and realized it when I was cleaning up the boat a few weeks ago. So, here is the new filler cushion :) .

    Formula 330 Cabin Floor & Ceiling Work

    Just looked at an old picture from when I had the ceiling/headliner down a few years ago . . . . . Looks like there is wood embedded into the fiberglass deck ONLY in the area where the dome lights are, so I'd have to figure something else out in terms of additional fasteners. Maybe hook & loop...
