    1966 40hp Big Twin to Suzuki DF25 on 14' SC holiday?

    It was never my intention to troll with the 40hp. At idle it is way too fast. trolling bags would help. If I kept that motor I would have hung my '97 Rude 4hp as a troller/ spare in case

    1966 40hp Big Twin to Suzuki DF25 on 14' SC holiday?

    Just afraid of it loading up being 2 stroke. My dad had an old 50hp, wouldn't idle that long before it loaded up and died

    1966 40hp Big Twin to Suzuki DF25 on 14' SC holiday?

    Agreed, it may not go slow enough, but it will idle for hours unlike a Big Twin 40hp, so a couple trolling bags will get me the 1.5-1.9mph for trolling lake trout that will land me fish. I have a 1997 Evinrude 4hp. An awesome motor in it's own right ( I have well under $200 into it running...

    1965 StarCraft Explorer Rebuild

    Also considering that ratings all changed from gross hp ( crank ) to Net hp ( prop ) by 1990 across all brands. Johnson/ Evinrude by '85 I'm pretty sure. An old 650 probably does not make 60hp at the prop. A 40hp would make about 35hp. A modern 30hp 4 stroke would likely be just fine. I JUST...

    1965 StarCraft Explorer Rebuild

    It's not uncommon, but not recommended. A 4cyl 650 does not weigh much more than a 4cyl 500, so it's not that big of a deal with a vintage motor My Grandparents had a 1963 Custom Craft Sea Ray bought new, and they had it repowered with a 1964 650 at the dealer 1 year later, so that it would...

    1966 40hp Big Twin to Suzuki DF25 on 14' SC holiday?

    I just ordered a new DF25ATS3, 10' control cables and a tach with engine function idiot lights for $4,700 I'm going to trade a little speed, for a little quieter operation, reliability and fuel economy. Also won't have to have a trolling motor as it should be able to slow fast enough

    1965 StarCraft Explorer Rebuild

    50hp Honda will be far too heavy.. An Evinrude/ Johnson Big Twin 40hp was probably the intended motor when it was new. They weigh the same as a modern 4 stroke 25hp

    2021 DF25 control cables?

    Are the control cables on a 2021 Suzuki DF25 the same as what was used on a 1966 Johnson Shipmaster control connected to a '66 40hp Big Twin?

    1966 40hp Big Twin to Suzuki DF25 on 14' SC holiday?

    I agree it's a great motor. I do have to eventually get another lower unit end cap. Someone destroyed the one that is on it, and gooped it up with alumi weld. It holds and the skeg is still good, but it looks horrible. Also the choke solenoid quit working, so the manual choke is the only way...

    Albemarle 24 - EFI maps and fuel return

    Water is hard on the sensors. A blown head gasket in a car can take them out from the steam

    1966 40hp Big Twin to Suzuki DF25 on 14' SC holiday?

    My 40hp Johnson Super Seahorse Deluxe is a great running motor, but being from 1966 and has had some float flooding troubles ( sunk cork float ), makes me cross my fingers when I hit the key and I won't go out without aux propulsion. It does start almost instantly every time, even getting...

    I think I'm another story of a bad boat purchase

    With a functional 4.3L, I would rebuild the boat.. Gonna guess 19'? It will cost ~$5k to rebuild it + your time ( Pro would be $100 hr at least ), but the boat market is so far flipped right now.. Covid made boating more popular than it's ever been but it also created supply chain issues and...

    Tell-take won’t start pushing water until warms up.

    well if you do have a cooling problem, change thermostat and impeller before you fry your motor and create more problems..

    Albemarle 24 - EFI maps and fuel return

    A spark plugs anti fouler from the parts store drilled out does the same thing.

    Albemarle 24 - EFI maps and fuel return

    Right, because it runs in open loop. Getting a sensor to live long enough might be a challange..

    Albemarle 24 - EFI maps and fuel return

    The spacer block ( you can drill a spark plug anti fouler fwiw ) will help the oxygen sensor live, but it's also going to skew the reading into being leaner than it should be . Your talking about sensors that are north of $50 being wide band

    Albemarle 24 - EFI maps and fuel return

    Keep in mind that the Holley Sniper IS USCG rated, but also that a wide band oxygen sensor needed for self learning will not survive.. Holley's software will have a tune close enough to make it run, but you will never dial it in

    35 hp Evinrude

    Quick and dirty way, you need a starter with a solenoid, a bracket and a push button starter switch. The flywheel needs the teeth, but I don't think they came without on the 20-35's.

    3.7 470 amazing

    They are a nifty engine. The 4.3L was cheaper and proved more reliable so any advancements were halted until it was finally discontinued in 1990... If Mercruiser kept tweaking it, they could have perfected it, but instead they forgot it
