[atlantic high]

Just purchesed a KANTER 45 , 1987 with a volvo penta TMD 30 A (90 hp) , I can't find any info on this engine, any one know if it had any problems and what I should watch for . The previous owner did no maintence, all he said is it dosen't leak oil and it doesn't smoke. There is 1700 hours on the motor, he said he had no problems so far. Any info on this motor would be helpful. thankyou . atlantic high
