    Riser Extension Blocks - Full Closed Cooling ???

    Quick Update . . . A bit of re-engineering . . . As I removed the old fittings, installed the plugs where needed, I did some test fitting of the riser extension blocks. . These are the kind that have 2 set of fasteners rather than the kind that use a long bolt thru all pieces into the...

    Riser Extension Blocks - Full Closed Cooling ???

    Picture time . . . :D I reminded myself how much I hate pulling apart I/O exhaust systems :rolleyes: . Anyway, I got the elbows off the port engine and will be proceeding to the starboard engine soon, which should go fairly quick, since I am now practiced up. Here are a few pictures of the...

    Replacing stringers.

    You can 'hear' all kinds of things in the Internet and elsewhere. If it is a bunk trilar, then it should be fine. A roller trailer, not so much. However you can add some 'bunk-like' supports to a roller trailer while rebuilding the hull.

    Mercruiser ECM Failed?

    Sounds like your mechanic has done the proper diagnostic proof. Although, it would be good to re-install the original ECM and re-try, just to make sure it was not a connector issue. There is a place or 2 that will repair ECM's for less that what a new one costs. . . . there might be a few...

    How do you match new trailer to existing boat?

    Yes, over thinking . . . poerboats are not that flimsy The bunks turned on end are common for many trailers as they require less mounting hardware to achieve adequate height above the cross members.

    Riser Extension Blocks - Full Closed Cooling ???

    BTW - i also plan on replacing the exhaust flappers . . . which are Merc # 807166A1. When I replaced them 8 years ago, I recall that they were a bit pricey ($50 each :oops: ). This time around I found some for about $25/pair . . . Of course, as I work on the engines over the years, I have...

    How do you match new trailer to existing boat?

    That trailer is quite generic and the odds are any v-shaped hull will fit fine without much adjustment, if any. I did something similar when I bought my 24 foot boat. . . bought the boat in NJ and the trailer in MA. Then took the trailer to get the boat. Just out of curiosity, I did take a...

    How do you match new trailer to existing boat?

    Most bunk trailers will 'find' their own fitness as governed by the main bunks. You may have to adjust the front bunks and bow stop, but that's about it. Roller trailers will do something similar, but they are probably going to be a little more finicky

    Riser Extension Blocks - Full Closed Cooling ???

    Speaking of masks . . . I got my 2nd COVID vaccine shot yesterday. The Admiral is still waiting to get her first, since she is just a sweet young thing and managed to fall just below the eligibility age bracket (for now). Back on topic . . . I am really excited that I got these particular...

    Riser Extension Blocks - Full Closed Cooling ???

    The parts have arrived . . . Looks good. Here they are, showing both top and bottom surfaces. One nice surprise is that the extension blocks have openings between the 4 main ducts as evidenced by the twist ties I inserted through one of the passageways. So . . . these extension blocks...

    89 Rinker Restore: Seeking suggestions for new SBC350

    Cam duration and lobe separation are important for a marine engine, because of the 'wet' exhaust. Less 'duration' and more 'separation' are good things for a marine engine. Google 'exhaust reversion' for more details. Essentially, at the top of the exhaust stroke, both exhaust and intake...

    Can you start these in cold temperatures out of water?

    As for the cold temperature question, assuming you get the engine running to check it out. . . You will need to winterize it immediately once tested. In 20-30˚ F temperatures, any remaining water inside the engine (usually about 3 gallons) will freeze within 24 hours.

    1987 Power Play XLT-185 - floors, stringers, and upholstery

    Maybe you can just use some acetone to pull up the wax layer. Sanding may not be the best approach, since it will tend to cut into the fibers of the CSM, and promote water penetration through the fiberglass layers. You can always do a pull test on a small area of the floor by seeing how well...

    Riser Extension Blocks - Full Closed Cooling ???

    After some search, I have found only a couple of parts like the one I prefer that look like this. . . an HGE 3320-APR which is an aluminum part - not my first choice, and XME 43320 which is in short supply. I'll see what I can get . . .
