Merci beaucoup ❤❤❤❤

I have the same motor just wondering if it's 50/1 or 100/1 fuel mix.

Same motor foe sure just the casing are diffeent really. The little nitch below the water exit cover is the locking mechanism for reverse

what happened with this md6a series? in the end you restaured this motor?

Please dimension hole of main jet .are 92?

Never ever try to open joints with a screwdriver , there are other ways.

Parsun is good

Your thermostat isn't hot so will be closed so flow will only mainly come out of one of the outlets. You need to remove the thermostat when flushing or the flow won't go all around the engine block and cylinder head.

All of the questions you mentioned are in the manual which can be googled.

You need the correct exhaust riser. (I have this engine) you can get a VP riser or an aftermarket Stainless one, both have some connections. The pipe coming out of the thermostat housing will go to this exhaust riser. The pipe coming out of the engine (near the air intake) will also go to this riser. If there is no water flowing out of your thermostat housing it is because the engine is not warm and the T-stat has not opened. You can remove the housing and T-Stat to test flow. However note that the gasket for this assembly is actually on the Thermostat itself, so it may leak a bit while you test that. The exhaust riser in this video is homemade (not bad necessarily) and does not have the connection points in the correct locations. Cooling water comes in from the sea, through the gear box, and THEN to the pump suction side.

i have a delay when accelerating

i have a delay in acceleration, the engine dont respond immediately, can you please do a video on how to adjust the carburator ?

Hello, how to adjust/verify proper level of fuel in the carburettor?

Lekker man! I have the same motor on my boat so this was very helpful!!

what a superb fix, thanks so much for taking the time to do this

A lot of the internal debris in the waterpassages is probably scale from the water rather than corroded cast iron.

Hey, thanks for the video! I am trying to fix mine but on mine it seems like there is a part missing on the cover that is a part of the carborator. It is a small hole straight into the plastic cylinder part where all the gas is dripping out. On yours it seems like there is some kind of ventil... it is located centered under the front cover, do you know what that could be? Feeling lost as there is no such part in the owners manual...

This video is a master piece!

Part 4 is coming?

Those pipes go to the gearbox

Brilliant commentary and illustration thank you

You are my new hero! I have a md6 which I am trying to fix (it over heats and struggles to start), and not knowing anything about engines I am using it to learn. So this is just incredibly helpful. Thank you.

You work on the water pump yet?

What engine were those piston rings for? Would be interesting to know as a MD7A owner

You could always empty the sump the hard way with your syringe then drill and tap a hole to suit a plug like a vehicle has. Or in the tapped hole you can fit a banjo bolt and a hyd hose thst a proper sump pump can get attatched to. Ive seen manual water pumps that are fitted to carsvans etc used and they perform just fine.

You def have to move the water injection point to the position you pointed to on your exhaust riser. Where it is in the video is oh so wrong.

I'm enjoying your series. It's a shame that engine had so much rust. I'm working on a MD7A in Virginia USA, but ran into trouble when a manifold bolt broke off inside the cylinder head, so now I have to find a way to remove the manifold. I think I know the techniques for that, but we'll see.

I bought custom bearings and rings for my engine, not factory ones. The size of the bearings was provided by the crankshaft grinding plant, similarly with the piston rings. The remade elements are not worse than the originals, apparently - we'll see.

Hello, I just finished rebuilding such an engine, I'm at the break-in stage 4 hours of work behind me. good luck

Are the clearances too big on the original bearings? If the rings you got suit a Subaru then surely the bearings are the same as another engine made sumwhere in the world. Those little engines get rebuilt here in NZ My engine machinist is away on Xmas holidays right now but Im pretty sure he would be able to find an equivzlent diesel bearing. Put the cylinder head in Evaporust to clean it Or look on TH-cam how to make your own Electrolysis cleaning tank. Easy to do and worx brilliantly. Do not at any stage beadblast or shotblast the head.

Have to be very very careful with the VA model injector pump on that engine. Extremely hard to get certain parts for them nowadays. Clean waterfree fuel is an absolute must with them more so than a standard type pump. I remove those factory saltware pumps and fit a pedastal type to remedy the issue tou have with them filling up the engine with water. Exhaust manifolds also fail due to being saltwater cooled so best thing is to fit a 3 way vslve on seawater intake so after a day out it can be closed to run the engine from a 20 litre bucket of freshwater. Also with the 3 way valve if the boat starts to fill up with saltwater you can close the valve and use the engine as a bilge pump while still motoring the boat.

Thank you. Very helpfull

where's video 2?

Thank you for the video. I just purchased the Aqua Marina 335 Aircat and am looking for a suitable small 2hp 2-stroke engine mainly due to the light weight of 10kg. In your experience will 2hp be enough power for cruising on rivers, lagoons and lakes along the Garden Route?

Thank you for the video. Really appreciate it

Хороший мотор ,немогу купить.Україна.

Ok the bes

69 Subs😝😝. Noice!

Thanks!

I had one like that, sunk it numerous times and it ran for decades without any trouble.

Donde encuetro repuestos de esosmotores

Henk, I have the same problem that you start this video with--I'm getting gas leaking out of the carburetor. In your case, was it the shut off valve that is actuated by the carburetor float, or was it something else? My motor had not been run in 30 years, but it started right up with fresh gas. Hoping to narrow down where to look, although I plan on taking the carburetor off and cleaning it.

Thank you for this video. Do you know if it’s possible to tighten the throttle switch on these motors? Mine will vibrate itself down to idle if I don’t have a hand on it.

Thanks man, I had to search a lot of places to understand the variable reluctance stepper motor but some queries were still in my mind. This cleared it, thankyou so much

Thank you Hank. Did you do all of the animation in PowerPoint? I am looking at making my own videos and trying to find out what is out there to animate videos. Any input is greatly appreciated.

Very useful. Thank you
