    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...

    Riser Extension Blocks - Full Closed Cooling ???

    I've ordered parts, so I'll see what arrives. I plan on digging into the exhaust over the next couple of weeks. . . adding the extension blocks, new flappers, etc.

    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 . . .

    Milky madness

    Just by the looks of the milkshake all over the engine and your description of 'blowing' the water out (which you now know didn't do anything except put some added wear on the impeller) - I'd say you have a total loss of an engine. Maybe it is just the exhaust manifolds that cracked and not the...

    Bravo 2 outdrive not engaging when in gear

    Yes, you/he needs to check for missing parts. I assume he never found the impeller in the lower unit. :unsure: :rolleyes: I would also think you may want to take the outdrive apart again and put it back together with the aid of the service manual. Does your friend wish he waited until you...

    Riser Extension Blocks - Full Closed Cooling ???

    I'd prefer to do something like this, but I'll be taking a look at the boat first to make sure about all of the bits and pieces. On thing I am realizing is that the shift linkage and electrical box may have to mount to the riser instead of the elbow ??? :unsure: Not sure if they will raise...

    Riser Extension Blocks - Full Closed Cooling ???

    Thanks for the info, Scott. It looks like those are dry-joint style, but my manifolds are old school wet-joint.

    Riser Extension Blocks - Full Closed Cooling ???

    I found the information in my Merc manual (#16). It does show that the riser would be part of the sea water flow, but . . . I'm thinking it would be better to separate the iron (riser) and the stainless steel (elbow) for longevity. So, I probably will go with the 'second' style riser that I...

    Riser Extension Blocks - Full Closed Cooling ???

    Hi Scott, How much taller are the 8.1 elbows? I'm thinking I need about 3" of additional 'rise' to put things above spec.

    Riser Extension Blocks - Full Closed Cooling ???

    I’m going to try to get the second kind that allows flow between the channels and see if I can router the ducts between the channels to be a little deeper than they are originally. To your point, AD I want to have the most flow through these parts.
