Hi Jonathan
It would be very interesting to get a good comparison of performance for 80
v 100 hp in the same airframe.
If you could assemble some before and after figures for take off roll,
initial climb and a 5 minute timed climb that would be good. Also be
interesting to see how fuel economy is affected. Obviously you would be
trying to get weight, wind and temperature similar.
I was considering a similar swap last year, but could not justify the
expense for the 2 or 3 days a year when our strip seems shorter than usual.
Regards
Pete

Subject: Europa-List: Re: Old Classic needs upgrade to 912S 100hp
Thanks Dave and I'll take your good advice. When I do the preflight oil tank
gurgling on my 80hp engine and then do it on a friend's 100hp 912S,
the difference in compression is very noticeable. Hence my concern about
whether the older starter motors can cope.
Anyway I've now purchased my 2nd hand replacement engine from Kevin Dilks,
sight unseen. Why do I have the confidence to do this? Well, his reputation
goes before him for restoring Rotax engines to near-mint condition and
another friend has found him to give excellent advice on problems, free of
charge and his suggestions work.
Also he was described to me as "a good chap" by no less than Neville Eyre.
Recommendations don't come higher than that!
Furthermore he's selling me a 230 hour engine which has been opened, checked
carefully and every conceivable part that needed replacing was done with new
components. I'm assured that when he says he's done that, you can bet your
bottom dollar that he has.
Finally my experience with Rotax 4-strokes tells me that provided they're
serviced and operated properly, you can place great faith in them.
I have no qualms and will be collecting the 100 horses on Wednesday.
