    1994 mercruiser 454 What oil/filter to use

    Keep in mind, the oil really should be a marine type oil, or a race engine oil, or just an oil with a high zinc content in a correct viscosity... Your 454 Chevy truck shifts into overdrive at ~55 mph and then cruises at 2k RPM or so.. Your 454 boat cruises at 3,500 or so unless you wanna go...

    6 Gallon OMC Metal Fuel Tank

    I think you would have to try hard and use way too much to do that.

    6 Gallon OMC Metal Fuel Tank

    There isn't any reason you cannot solder that crack.. I was thinking you meant it was split in half, in which case soldering it together, or as others noted just patch it with rubber hose... But the crack the way it is. sand it with fine sandpaper, apply some flux and solder it with plumbers...

    How to build back to back seats.

    Some of the early 60's SC runabout's DID have bench seats as an optional floor plan.. I would buy the Wise seats and build 6" bases for them. I put them in my '66ish Holiday 14 OB but the 8" bases they come with are a little too tall for the boat. My boat had 2 fisherman benches, but they...

    6 Gallon OMC Metal Fuel Tank

    Looks like used only at this point and a $$$ item at that. Cheaper to buy a new tank. But you can solder copper.. Run a fish wire up the tube to use as a reamer and solder the crack

    1948 FD??

    Alumacraft knows I would say. Very few companies would have that information, let alone bother to give it to you. Alumacraft is one of the few companies that will.. They must have had at least proof that production went back to 1947 for that hand written document to be made

    Help! Can't find HIN on Chris Craft Scorpion 210

    I think the requirement was/ is to put the HIN in 2 places. One hidden, and one in the standard spot on the transom. Only one of my boats is new enough to have a HIN, and it's my parts boat. I found a tag under the dash with the HIN while ripping out the cluster and controls

    Pre red plug Simplex controls to red plug motor?

    That's what I was thinking, but I didn't know if OMC ever had an adapter harness or has an adapter harness like they have for the Red plug motor to black plug controls or vice verse adapter harnesses Did the motors prior to 1973 have any single point disconnect from the harness? Mine has...

    Pre red plug Simplex controls to red plug motor?

    I have a 1966 RD-28 40hp on my 1966ish Starcraft Holiday 14 OB. Runs great but I discovered it needs lower unit seals ( ordered ).. It did get me thinking on, the what if something happened to it and it needed serious repair.. I have a spare 1988 Johnson 20hp which is ready to go, other than I...

    What year outboard is this Super Seahorse 40hp?

    I just and went and re changed the gear lube to flush out any water remaining and realised where the extra lube had come from.. I simply pumped a couple pumps extra past full and let it run out, not giving any thought to the fact it was running down the leg... But now everything is wiped off, if...

    Boat Flooring

    Any "X" rated plywood would be good to go once properly sealed. Marine plywood is simply AAX rated but you could use ABX without any thought to it, or even CDX or BCX if you didn't mind filling in some gaps from knots with water proof putty... Laminate flooring absorbs water as it's not really...

    What year outboard is this Super Seahorse 40hp?

    I got the parts ordered, all OEM. Just got anything that said seal or gasket from the gear case IPL.

    What year outboard is this Super Seahorse 40hp?

    nope, coming out the water intakes on the opposite side.

    What year outboard is this Super Seahorse 40hp?

    Yes, I know. I'll get the parts coming. I figured I'd replace the shift rod or ring too. Is the prop shaft seal diffacult like a Merc or is it simple? It's not leaking right now. I have a pressure tester that I manufactured out of a bike pump but I pretty much know it's going to leak. Looking...

    What year outboard is this Super Seahorse 40hp?

    Ok so I just changed the gear lube. Not much water was in it. Was in the lake about 1hr in total. I refilled it, and it looks like more might have came out, but that seems impossible, since it's only going to leak to the bottom of the seal. Pouring right now or I'd drag it out of the garage and...

    Value of a 1970 StarCraft Chieftain

    You may be right. I just looked and at least up to 1969 they were Starchief but continued some time after 1970 as a Chieftan.

    Value of a 1970 StarCraft Chieftain

    If your looking for strictly resale, probably NOT.. Your going to need at least 90-100hp to make it happy... But that is a rare boat and it WILL sell. especially with the shift to outboards

    Value of a 1970 StarCraft Chieftain

    Starchief was early 60's, the Chieftan was the next generation of the same boat

    Value of a 1970 StarCraft Chieftain

    Being an 18' chief outboard I'd have to say he can probably get $3k for it as it's one of the more popular and rare hulls.
