"I have a 1987 Tamd41a in a 28' Cape Dory SF. At 2100 hours had a transmission failure. Problem worn cone gear. Rebuilt locally and ordered replacement coolent tubes. Got updated tube replacement kit [10 pieces] from Volvo While I was at it replaced the HP oil lines for remote oil filter,fuel lines[2] and Jabsco impellor [2 years old] Problem; I have increased the engine temperture by about 10-15 degrees and lowered the oil pressure by about 10-15 lbs. What happened? Thanks in advance for any help.
