This section is so big it had to be split up

each section has several hires photos that take about just a few secs to load

the Vire 7 rebuild and electrical arrangements are here in colourful depiction.

I based my rebuild on the vire 6BVR experience gained last year, and bought a good donor engine for it, then spent a couple of days rebuilding it taking photos imbetween and fetchingh new bearings etc over a few months.

People shouldnt chuch the unreliable engines out as

a) it is going to cost thousands to replace with a diesel and carpentry/shafting

b) it is always simple things wrong, like too much oil in the fuel, blocked water way or a badly adjusted carb that need fixing.

The vire engine was purpose deigned for marine use although the 2 stroke piston probably derives from E. German cars. As such it is cool, simple, reliable and about the smalles and lightest engine with gearbox you could ever fit inside any boat, and there is no replacement for it's size.

If you were really in trouble, you could yank it out, carry it in your arms to the dockside marine engineer and have the unit repaired economically in his shop rather than pay him to row out to your ill-equiped vessel. Much easier to do a winter renovation than any other engine, because you might as well do it in your garage with simple tools, whereas other engines require expensive boat visits or precision tooling.

Anyway petrol may be a fire risk, but there is plenty of water nearby!!

apparantly diesel 13hp engine will produce more vibration, more difficult to start, and cost more in fuel / have less range per tank than the vire, plus diesel bugs could make you ill and the stuff makes the whole boat smell.

Is there a better small boat engine that is not diesel???

Originally I inherrited a vire6BVR in my boat in 2002..

I had a bit of play in the crank pulley (up and down 0.5mm), it kept seizing, and was rumbling badly -

Prevention

I expect this was because of water ingress into the crankcase from the previous owner who probably forgot to shut off the water intake before stopping the engine - allowing water to seep through the exhaust into the cylinder, or possibly wave action/condensation coming up past the exhaust  goosneck?

Anyway it needed doing, and fortunately I had a couple of spare engines to strip before the real thing.
