    Old manifold question

    So, I've taken a short break from troubleshooting my new salvage engine. I may have a bad manifold, so have been on the lookout for one on Craigslist and OfferUp, just in case. I am going to "acetone test" when I finish all the "get ready for winter and rain" chores (I'm in the Pacific...

    Sheared water plug on block

    So, I was removing the 1/4-20 plug on the engine block (250 inline 6) to drain water from the block. I thought the plug was backing out, but then I noticed that it has sheared off about 3/4 of the way in. The top 3/4 of the plug came out fine, but the bottom 1/4 is still in the block. I am...

    Inline 6 250, 165hp water in oil

    The "new for me" inline 6 came off an old timer's boat that had been sitting in a garage (apparently heated) since he had some health issues several years back. My "free boat" had a cracked block. I checked the dip stick when I got the engine and it was "only black", no sign of water...

    Mercruiser 165 riser elbow plug

    I switched out a bad exhaust elbow for a newer one that I have. The difference is that my engine is setup for "reverse flow" on the coolant line, so I need to put a 1" MPT x 1" hose fitting into one of the pipe plugs on the new riser elbow. The pipe plug is not cooperating. Wouldn't budge, so...

    Mercruiser 165 shift cable bellows

    So I have a free boat that is actually looking to be not too bad. I have a running engine on a pallet that is almost ready to install. The last owner told me the leg was recently rebuilt before he left the boat sitting because of what turned out to be carburetor problems. I just removed...

    Mercruiser 165 distributor breaker plate

    The breaker plate on my salvage Mercruiser 165 (Chevy 250 Inline 6) is looking pretty crummy. The Mercury part is 33665 but is NLA everywhere I've looked. Would an automotive Chevy 250 breaker plate be acceptable? I know that the "marine" distributor is different from the "automotive"...

    Mercury 500 50hp, 1976

    So I have an old Starcraft aluminum boat with a Mercury 500, 50hp electric start (1976 according to the S/N). It was getting a bit warm, so I replaced the water impeller (toast) and got it all back together. Of course, when I was so excited to finally try it out, the key broke off in the...

    Mercruiser 160/165 exhaust elbow

    I'm scavenging parts from a Mercruiser 165 (Chevy 250 with a cracked block) to complete a Mercruiser 160 that I got from a salvager. The 160 is very clean - no grease or grime, oil is very clean. I really just need to get the wiring figured out (the main plug is different), get points...

    Mercruiser 160 carburetor

    My "free boat" had a 165 Inline 6. The block was cracked. Removed and disassembled the engine. Most everything looked good except the block. The carburetor is a little cruddy, but probably serviceable with a rebuild (Rochester 2GC). I bought a 160 from a salvager that looks really good...

    Mercruiser 160 "reverse flow"

    I got a 160 from a boat salvager. Looks to be in really good shape - just need a couple of items to try and run it before I put it in my "free boat". I need to get the cooling reconnected. I think the last owner was in the middle of replacing the riser/elbow but didn't quite finish. The...

    Mercruiser 160 mystery electronic ignition

    So I got a Mercruiser 160 engine and outdrive for $200 from a salvager. Looks to be in very nice shape - it was in a boat in a garage for quite a few years. So I want to use it to replace a 165 with a cracked block. I want to get it running before I install it in the boat. I need just a...

    Mercruiser 160/165 cracked block

    Got a "free boat" with 1974 Mercruiser 165. The outdrive appears to be in very good shape (said to have been rebuilt about 5 years ago). The boat has been sitting for the last 4 years - not winterized, and it got in the 20s for several days at a time, several times. The engine had about 4-1/2...
