Nice job that looks like a beautifully restored older boat. Love the simple Chevrolet small block. Only thing I might do different is use ear muffs for water supply instead of the bucket because the water has to travel up and forward quite a ways to reach the engine mounted impeller. A pressurized flow will reduce the risk of dry starts. When the boat is on the water it’s a non issue because hydrostatic pressure fills that hose leading to the impeller. On my 1988 OMC/Chevrolet 4.3 I use the Mercruiser round muffs with the metal clamp that goes through the water intake holes, these are the best fitting ones I have found. Usually my engine will fire up after cranking it over 3 times after it’s 6 month rest
pretty good video, on my boat, I got rid of the mechanical fuel pump, and install an electric with a push button override that bypasses the emergency fuel cut off switch, so I can prime the carb without cranking the engine, plus I installed a 4 bbl holley with an dual plane intake, after doing that, I gained 11.5 more MPH at 3/4 throttle.
The water is sucked and discharged through the outdrive as shown in the video. Inside the motor compartment, the water suction hose is connected to the outdrive through the transom shield as shown in my video about boat winterization.
It connects to the fuel pump. In case of breakage of the diaphragm which is inside the pump, the fuel would not spill all around but it would be sucked through the flame arrestor into the carburetor, flooding the engine and stopping it.

Oil ?
Thank you for the video. Could you please tell me where do you connect the hose that provides the circulating water?
The water is sucked and discharged through the outdrive as shown in the video.

What does the blue hose on the flame arrester connect to?
It connects to the fuel pump. In case of breakage of the diaphragm which is inside the pump, the fuel would not spill all around but it would be sucked through the flame arrestor into the carburetor, flooding the engine and stopping it.
Ma una versione anche dobbiata in italiano?
Which outdrive is on this engine? I have a similar engine that needs an outdrive.
Outdrive is 290A

Ffs. Or buy a diesel. Or a new engine. It’d be quicker
