    De rigging a 1966 Super Seahorse Deluxe 40hp?

    The next town over has a '61 Dorsett Catalina with no motor for $300. Would do ok with the Big Twin 40hp... But I have too many boats and don't need another restoration project

    Aluminum and fiber glass

    plywood that has started to check, has gotten wet and is starting to fail. However, yes it would work fine. But sanding and then just using epoxy resin would work too. Follow with your paint

    De rigging a 1966 Super Seahorse Deluxe 40hp?

    Being a '66 it's permitted to use 50:1. It runs great. Just time to bring the boat up to date for my purposes.

    De rigging a 1966 Super Seahorse Deluxe 40hp?

    I'm repowering the boat with a brand new 25hp Suzuki, so yes all of the Johnson/ OMC stuff is going.I'm fairly sure that this boat came with this motor.. The previous owners put in a battery disconnect which looks like they did it cleanly but I've never looked at exactly how they tied it in...

    Never underestimate the power of the mechanical fuel pump

    The way you bump pressure on a mech fuel pump for forced induction was to boost reference the weep hole, which puts pressure on the diaphram and causes the pressure to rise 1:1... I wonder if the weep hole got plugged by insects. If it couldn't vent, it could hold pressure ontop of the diaphram...

    De rigging a 1966 Super Seahorse Deluxe 40hp?

    Ok, that makes sense.. And the harness that runs up to the ignition switch should be one complete harness right? So that will terminate from the junction box to the dash.

    kicker bracket small area transom

    You won't need 10hp. 5hp will troll that hull just fine. I would put 5hp on a bracket, so that the powerheads don't clutter up the transom so much. You could clamp a 5hp to the transom most likely. Looks like there is enough room

    De rigging a 1966 Super Seahorse Deluxe 40hp?

    I know that the wires under the cowl need to be un plugged first, since it is a pre red plug motor, or do I keep it connected on that end and disconnect from the front? This motor has the charging box as well, being its's a Deluxe with charging circuit although I don't think it works.

    Towing with/without Overdrive

    That's a 5R55S, which dates back to the A4LD. I would for sure pull it out of OD. Towing in OD would get the trans a bit warm, and then they tend to have solenoid problems that you will feel with a reverse delay and eventually get an extra neutral when you loose reverse

    Towing with/without Overdrive

    Agree. Use tow/ haul if you have it... IF you just have an overdrive switch, for sure switch OD off... And if you have an older Dodge, keep OD off all the time and the trans will last forever

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

    I did figure out that the 25hp and 30hp differences is only the ECU and a throttle body restrictor vs a spark arrester. $600 in parts + voiding the warranty most likely. I would have gotten a 30hp, except Zuk does not make a 30hp short shaft.. I won't void the warranty so I'll leave it as...

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

    The issue was not knowing how good it was without knowing what to look for what wasn't, if it wasn't 'good'. It starts almost instantly, I've had it in the bucket running for hours but it does start to skip and pop after a while, but clears right up with a little throttle. Seemed to be fully...

    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?
