- Grand Banks 36' Classic
Hi, Russ here
I too have been reading for awhile and thought it was time to join. We are making the jump to the "Dark Side" and leaving many years of sailing to purchase our retirement vessel a Grand Banks Classic 36. Yesterday was the survey and sea trial. Things went mostly well, I could not believe how smooth the boat ran, how quiet it was and I was surprised when we hit 10 kts at the full power run. (the boat is a 1977 with twin 120's) after 35 years of sailing even the relaxed 6-7 kts seemed like we were flying. Now I have to refresh myself on driving twins after years away from the helm of a power boat.
Except for the wind, and the rain, and the small craft warning..(we boat out of Sturgeon Bay, well Little Sturgeon Bay WI) it was a good trial, until questions came up from the surveyor about the engines. Maybe the intro is not a good place to ask these but his concerns and the back story are:
Boat has been used last 2 years as a floating cabin by the PO's. They are much older and she does not get run much besides started weekly. Okay so start up had some blue smoke / white smoke which I see is common, little bit of sunburned fuel on the water from the exhaust. As expected there was white smoke as the engines heated... they got stable at about 160-180 degrees and all but the slightest trace of blue remained for the remainder of the sea trial (we did send in oil samples to be tested) the real issue came after the full power run up - - it might have just been to much, and with the boat maxed out on hull speed to much fuel was going in but we pretty much fogged for bayflies with gray - black smoke rolling for both exhausts. When we returned to idle things seemed fine with only a slight blue smoke from the starboard engine, port was clean. I know there Ford engines are a little different.. do they have regular injectors at the head, or is that function from that injector pump block? There is also a ticking that was not there on a cold engine (oil pressure seems good both engines) from the port engine that to my untrained ear sounds like a valve or lifter... it did not sound like a knock and the surveyor is concerned its a rod which I find odd. Overall we like the boat, but he has now suggested calling in a second person to do a full mechanical / engine survey.
Any idea on the above? Could the black smoke just be blowing things out from lack of use.. ? I know the engine has solid lifters, and they should be lashed from time to time, could that be my noise?
I hope in a week to be a full time person on the Forum as the proud owners of this neat older boat...
Your help is appreciated..I spent years on a Catalina forum and the information shared was priceless...
Thanks
Russ
