As far as I've been able to ascertain, the 2GM20F was installed as original equipment when our boat was commissioned. ?I'll have to go back to look at my documentation to see if I have any original dealer information etc. Based on Yanmar's specs the 2GM20 isn't really -that- much larger than the 10GM10. ?~100mm longer and ~50mm wider and 23b heavier. ?Our engine compartment is snug, but I'd have to look at Mark's boat, the other S2-27 on our lake, to compare to the 1GM10 equipped boats to see any difference. ?I just did a major service on the engine and sucked out and replaced all fluids-engine oil, heat exchanger antifreeze, and transmission lube, replaced both fuel filters, installed a new impeller, replaced the engine stop cable, and had the mechanic do a thorough going over of all systems. ?For a 1980's vintage boat, she's doing remarkably well.
I'm not the original owner, but thanks for thinking I would be that loyal and long term thinking. ?I'm pretty sure I am the 4th owner of this particular boat. ?She started out on the Great Lakes, was moved to the Neuse River area in North Carolina, and I moved her to Tennessee.
