When I bought the boat last year the motor seemed to be running hot. Made them fix it before the sale. They replaced the therms. The seller was told the therms needed to be upgraded. Apparently there was a upgrade on the therm housing? Anyone know about this? Anyway new therms. Gauge still reads hot. No alarm. Mechanic tested the temp of the block. Gauge bad. Question : upgrade on the housing or b.s. Cost the seller about $500 for the new therms.<br /> Thanks, Dead Eye
