repower to a 2gm20?
After pulling my A4 , assessing the damage (seized from a stuck valve, very rusty, generally ugly), adding necessary goodies (fresh water cooling, electronic ignition, electric fuel pump) and considering the cost of boring and balancing, I've found that a rebuild will set me back almost $2000. This doesn't include time ( that would be better spent working on the actual boat).
The Irony is that I was just offered a used yanmar 2gm20 for $2000. This puts me in a bit of a conundrum as I know that going with diesel would also require me to completely change my fuel system (tank is shot anyway so maybe thats not so bad) making the project cost something like $3200 - 3500 (the seller said I'd also need to get a longer prop shaft but I don't yet see why...). I didn't see or ask the condition of the yanmar, all I know is that the guy has two of them equally equipped for the same price. He also said he's repowered two other t30's with these engines. Just when I think that I'm dead set on one thing (rebuild of the A4), another pops up. What do you guys think?
