An alternative to original style boat motors is an air cooled Chinese diesel. You save a lot of weight and money. Reliability is so much better without salt water cooling. I have the smallest 168F diesel, and it is superior for keeping the battery charged and small output to an existing prop. There are a variety of larger sizes too, but I encourage boaters to shrink horsepower. Tips: Mount it on a thick aluminum plate. Avoid lowest idle and zooming over 2000 RPM. Watch oil consumption during break in as it will be very high. My 20 MM shaft wants an inch adapter to fit a seven inch pulley and a drive coupler.
I haven’t heard of these Chinese diesels you speak of. Air cooling would be tricky as there is no easy way to vent the heat on my boat. Interesting concept though
@@OnnoKok Sichuan Sifa MB168F. It has top quality castings, steel gears, and meticulous measurements. Air cooling? Dry hot air. Open the front hatch. Open the companionway. Run a fan. A small price to pay, to satisfy the gods of reliability and lightness.
@@stanleybest8833 I had a look at a listing for this engine and although it is described as a diesel it has a spark plug and a 5.5:1 compression typical of a petrol engine. The power is 4hp, which makes it suitable for a small boat of maybe 4 metres length. The output shaft is a double v pulley which may be a problem to connect to a conventional marine gearbox.
@@RodFleming-World thank you. My biggest fear is not noticing a blockage with the raw water pump or something. I’m going to be adding a water temp alarm in case it overheats.
@@OnnoKok good idea. The alloy cylinder head will definitely warp if it gets too hot and then, no end of bother till you get it skimmed/replaced. They like to run quite cool, these things. You've got a nice big engine room which will help with that. BTW if you have a thermostat in the cooling circuit, use a 160 F rather than 180F. (Some people just sling them but strictly you should use a blanking plate with a 1inch hole to maintain design pressure, if you do.)
hey man I hay a choey lee 41 in rock and roll harbor and I'm i the exact same situation. I need to repower and I'm trying to navigate how and where etc. I would love to buy you a beer and pick you brain. or a decaf mocha latte or whatever. awesome video. arrrgh.

All this makes for great UA-cam content. I’m sure you’re happy that your stress keeps us all entertained.
At least the stress is good for something... lol.
Just finished your New York to Florida trip vids. You need more subscribers! People are missing out!
Slowly, slowly they are coming. Thank you very much for watching. Soon I’ll be able to get back to sailing videos
How great does that new motor look..and a lovely clean engine bay...👍👍🍺⛵⚓
Thank you so much! It’s still looking sharp after the first 200 hours of run time. Hopefully things stay this clean for a while.
I can’t believe you installed that by yourself. Amazing!
Wasn’t what I was planning to do, but it worked out thankfully.
Great job. Never give up!
Thank you so much! I appreciate it.
Nice video! I was curious to know how you did everything with the new engine. Thanks for sharing!

@@huffyhoosit Wrong. You read the wrong ad. At least that is what you are implying. Shape up.
Tremendous access in that engine room.
Yes, it’s great to be able to get at both sides so easily.
@@OnnoKok with the Isuzu, don't ever let it overheat. They're good solid motors but they don't like to be abused. I know you wouldn't and all, but...

@@RodFleming-World the thermostat that came with the engine switches at about 176°.
Yeah!! Good job!!
Thank you so much!
Beauty, whats the make of the motor?
Hola!
It’s an Isuzu C240 engine

Oh man, I’m so sorry that I missed this comment. I’m no longer in San Diego. Did you still need assistance?
Hello, great upgade! how many HP in the engine? its a 40 ft sailboat?
Hello and thanks for watching. It’s a 55hp 2.4l diesel and the boat is 45’.
All di time. Penny wise and pound foolish
How much did the new motor cost you ? Nice access and a nice engine
Thanks for watching! The new engine cost $8,250 and came straight from the factory. Was built only a month before I ordered it.
😳💪🌞⛵️
