Alternative Solution is here!!
The BUKH DV8-10 is no longer being produced. I believe most parts are still available thru Bukh distributors except recently we learned that the saildrive gears cannot be had. During an email exchange with Simon Gregoire (Colibri CAN 224) I learned he had a damaged gear repaired. Here is a cut and paste from him: Thanks Simon! I had a saildrive gear tooth broken off so that less than 25% of it was left. They rebuilt it so perfectly I could not tell which tooth had been broken off even with very close inspection. The gear came back looking new. I was told they didn’t weld the broken tooth back in place, instead they rebuilt it from the base up with new material and then they grind it down to perfectly match the other ones. I still sent the broken tooth to them so it’s easier for them to create an imprint of what they are trying to match. Here is their address: United Welding Processes (Montreal and Toronto) http://www.uwp.qc.ca/en/ |

Bukh is not running. Little compression hand cranking the flywheel. Fair amount of air blowing out the intake port while turning the flywheel. Valve lash exists in that the rocker moves freely on compession and lifts the valve on intake, same with exhaust valve. With the head off and intake valve out, valve seat has some pitting. Seatis carboned up at the valve shield area.
Is this a "cut the seat and replace the valve" repairor should I be looking further. |

Yes this is a cut a new seat and replace valves... typically the exhaust valve is usually worse for wear. Check valve guides so that they are not loose, they can be changed easily. Be sure the head isn't warped as it may need to be milled. Make sure you remove the water jacket cover near the bottom stb side. It like to clog up in that area. Doing this and re installing with a new head gasket usually gets it right. Verify cylinder bore looks good.... meaning no unusual wear occuring. A ridge at the top of the cylinder is ok. Goodluck!

I pulled a real basic test. With the head laying flat, valves up, I poured paint thinner(teaspoon) on each valve. intake valve leaked all of it into the intake port, almost nonein exhaust port. This motor possibly over revved and maybe bent the intake. Source for a intake valve? Do I need to pull the injector before valve seat work?

I've never been able to remove the head from the block without removing the injector....so not sure how you did that but yes remove injector before any further handling(don't lose the copper gaskets under the injector). Keith Strutt is the Canadian distributor for BUKH parts... hes a good guy and knows this engine well 613-634-8100

What is the trick to removing the injector. It is pretty firmly planted in the cylinder head.

Once the nuts are removed, just use a large screwdriver to pry the cylinder out of the bore

Intake valve has a shield. Is this sheild to be oriented such that it diverts intake air away from the injector or does it face the other way.

Seems, on relooking, the sheild is oriented either up (flywheel direction) or down (back/bottom of engine). Ideas?

Hmm I can't remember, I thought the swirl flap faced the intake. Call Keith Strutt at 613-634-8100 he rebuilds these engines all the time. The washer inside locates itself on a pin, then your left with only two possible positions as I remember

Thanks, looking at the spring guide (washer), the slot is cut of-center so I will use that as the guide as to which way the flat on the valvestem faces and hence, the swirlflap. Hadn't seen one of those before, nor had the machineist who has heads stacked all over the place.

just remembered, if there is another Laser 28 near you...just remove the air filter and look in the port you will see it

Why didn't I think of that. We are still planning one more sail before we drop his stick for the winter. The "one more sail" is because you can't put a boat on the hard if there is still beer in the cooler.
