I just bought a used boat, and it has a 280 out drive, after testing it out, and the question comes to mind, is this outdrive strong enough tilted for trailering, or shound I get a bracket, I checked the volvo website, but could find any info, the boat is a Bayliner 19 foot bowrider and the engine is a AQ225D, everything runs great, now for a few questions; this boat has points, is there a drop in electronic dist. that has the same volvo advance curve curve, and after reading some posts here about the oil, I'm under the inpression that I should use 30w oil, what about 30wHD, I understand the HD stands fo High Detergant? or Heavy duty?, anybody knows, last but really inportant, Serloc or Clymer manual?
