    Easiest engine drop in replacement for 1986 MCM 470

    I was under the impression the 3.7 used a Chevy bellhousing bolt pattern but could be FOS Maybe @Scott Danforth or @nola mike may know Scott and Mike - OP wants to swap his 3.7 for a 4.3 (preferred or maybe 3.0) does the 3.7 flywheel cover (alpha one gen 1 drive so later mount spacing) fit a...

    Easiest engine drop in replacement for 1986 MCM 470

    I think the flywheel cover unless it is pre 1981 is should work. when the transition around '81 from MC1 to R/MR/Alpha one happened merc changed the distance between the rear motor Mounts. So unless you have a mc transom housing it should fit. You will need a wye pipe and yes easiest way is to...

    Easiest engine drop in replacement for 1986 MCM 470

    If it will fit in the doghouse or engine compartment a 4.3 will work great and be a power and reliability upgrade especially if you get a Vortec one with a 4 bbl carb (220 hp). If you don't have room a 3.0 will drop in and if you go down 2" in prop pitch work with same drive gearing. The 4.3...

    Prop questions on a 16' 1976 StarCraft Montego (Merc 888)

    Never used any of the composite props. If you have one sure why not use it. I suspect if they were better you would see more of them around. Sounds like you are up to speed on the other issues and possible pertronix stuff.

    83 Chevy 350 SB valve springs w uneven heights? Is that normal?

    Assuming they are the same spring they should have the same installed spring height. Not sure if that height is correct for the spring in question, which is key to having correct seat pressure on the valve. as Scott Danforth pointed out - are the valve stems at the same height when installed...

    Prop questions on a 16' 1976 StarCraft Montego (Merc 888)

    Any of the entry level Merc/Quicksilver Black Max, Michigan Vortex or Match series props will work. Since the original was a pressed hub you may need different thrust washer vs the newer style replaceable hubs If it has an automotive intake just watch for corrosion in the water cross over. I...

    replace coupler or not?

    Chisel or cut the old ring gear off , heat new ring up in the oven it will drop on the flywheel and make a friction fit when cool. i would send that flywheel back unless the ebay add specified some teeth are buggered

    Can't remove 5.7 vertically.

    nice. Nice to have access to equipment like that. When I did mine our rigger we used at work hooked me up. Sent his son over on a Saturday with a 15 ton crane….took longer to set up than do the pick

    Prop questions on a 16' 1976 StarCraft Montego (Merc 888)

    The aluminum could be rehubbed by a prop shop or just by a new black max or similar in same pitch. By the stamping on it it has been repaired already which is no big deal but sounds like PO liked the bottom of the lake too much I doubt he was hitting 60 unless he was towing it down the...

    Towing Boston Whaler 130 with Honda CRV

    I think you will no issue with either. Use your head when towing in terms of speed and following distance and make sure you have the boat situated on the trailer for 7-10% tongue weight. I doubt you need to add brakes. Most states require this for trailers over 3 k you are way below that...

    83 Chevy 350 SB valve springs w uneven heights? Is that normal?

    Looks like you are using different height retainers and or keepers on the valves. I ran into a similar issue on a 389 Pontiac - you never know what someone did on an older engine that has been apart. Would take them apart - valves could have different stem lengths, seats could be receeded in...

    06 4.3 mercruiser no start

    Does that have the correct wire colors for the slave solenoid? Maybe some one used a aftermarket replacement ? When you get your circuit tester or volt meter- look for power where BT mentions it.

    Gear lube poured out of gimbal bellows (Alpha 1 Gen 2)

    looks like some moisture has been in the ujoint bellows. any corrosion near the seal will kill the seal in short order I would do the u joints while you are in there. If they have the internal clip MOOG 315G or equivalent will work

    What's the best prop size? - 22 ft tahoe 228 Merc Alpha One Gen II 220 HP

    if relatively identical prop dropping 2" in pitch should raise your RPM 400 or so at WOT. If you are new to swapping props that is another reason to stay with Aluminum. I cut my teeth trialing aluminum Michigan Wheel Vortex 4 blade props on my old boat, which was a small 17 ft Bowrider...
