But I really doubt you would be able to mount a gearbox. the sleds of that era almost all mounted the engine from the bottom and only needed an internally threaded crankshaft to mount the clutch. You may be able to use one of the plate mounted belt drives. The 377 was a good running engine but I will pass along one big warning. We sold some 377 powered Ski-Doos 2 of which returned at the start of their 2nd season not running. They both had the worst internal corrosion of any engines I have seen in 35 years of repair work. I have a theory as to what happened but I can not explain why it only happened to the 377. I believe the failure was caused by a combination of synthetic oil and oil injection. Oil injection works off both rpm and throttle opening. The system pumps very little at closed throttle low rpm. On the other hand pre mix always carries enough oil for the engines highest demand. So on shut down with premix the engine is pulling in more oil than needed, its not burned as the ignition is off, so it is left to coat the inside of the engine. Oil injection backs oil delivery way off at shut down and may not be coating internal parts as well. combine this with synthetic oils reduced resistance to corrosion and it ruined the top end of the 2 engines. Now I don't know about other parts of the country but in this part of the northeast snowmobiles are often among the most neglected machines on earth. Many times they appear to be left right where the snow melts out from under them. They would come in the shop full of leaves and mice and with the seat covers rotted from sunshine. I do not think I would buy any airplane engine sight unseen unless the deal included at least a short term return policy.

When we went to the new lithium batteries the increase in performance was dramatic. This technology is now finding it' way to cars and motorcycles. I believe the motorcycle version is supposed to start a 500cc engine at .8lbs the car version starts at less than 2lbs. I plan to do a bit more research and if the charging system is compatible buy one for my track car. When first introduced the price was 1200 but has dropped to less than $200.

When the engine quits they are a valuable tool to use for landing where you want to touch down. Ipracticelowering the flaps while lowering the nose to maintain air speed thenraisingthe flaps andraisingthe nose. Do this a few times on approach and watch how much the the touch down point will change. If your model Kolb doesn't have them oh well, you are missing a great tool. > > I normally land with one notch of flaps and some power. When I was landing at my short one way strip I could always cut power and add flaps if I misjudged my approach. If I was landing with no power and full flaps I would have fewer options. Another point is that landing with power and one notch of flaps feels just like landing with no power and no flaps. I cut power and added flaps a few times when I gotsurprisedby a strong wind pushing me down wind into my one way strip. > > > The FAA doesn't like this but it works well in a Kolb. If you loose power use the flaps to fine tune your approach then raise them for landing. You will have a mucheasierround out (flare) at a time when you may need easy. Another point is that you can get the tail down first if need be to stay up right in unprepared surfaces. With flaps down it is much more difficult to get the tail down first. I used this technique to land and stay upright in a bean field a few years ago. The beans grabbed the tail wheel kind of like the hook grabbing a wire on a aircraft carrier. > > As always worth what you paid for it. > > Rick Neilsen > Redrive VW Powered MKIIIC > > [b] Good point. Years ago when I converted the MKIII from pre-mix 532 to oil injected 582, unbeknownst to me, the oil tank had a spider web tucked away in one of the upper corners, apparently collected from years of sitting on a shelf. A couple months later, when it finally detached itself and blocked the oil feed line to the oil pump, me and #1 daughter suddenly found ourselves in a quiet airplane about 1,000 agl and on final for a miniscule R/C airplane strip. (Thank you Lord, perfect spot!) Used the stick to maintain airspeed, and flaps to control the descent, nailed it and got it stopped in the available distance. Obviously a better pilot might not have needed the flaps, but they are an excellent tool for dealing with engine outs, and they work for that exactly as Rick says. -------- Richard Pike Kolb MKIII N420P (420ldPoops) richard (at) bcchapel(dot)org Kingsport, TN 3TN0 Now faith is the substance of things hoped for, the evidence of things not seen.

Internet replacement batteries can be purchased I got a price of $14 for a 4.5 ib 12volt battery very nice . thanks again Chrisp.s. do you know anything about the SkiDo 377s ? > Chris, I don't have any experience with SkiDo 377s. I did weigh my prototype LiFepo4 battery, and it came out at 11.4 ounces. This includes the original four cells, the two wood mounting brackets, and the connector strips that were welded to the cells. It will put out 70 continuous and a 120 ampere pulse for 10 seconds. It is rated at a 2.5 ampere battery. The MZ 34 starter pulls 30 ampere continuous, so this battery will crank the engine for about five minutes. The properly primed engine usually starts in about five seconds. Jack B.
