My 30 Sundowner was repowered from the 54 hp VW to a 80 hp Cat 3034T (Perkins M85T) 2,400 hours ago. It runs easily at 7kt at 2,000 rpms, burning 1.6 gph. It will go up to 2,600 rpms and 8.1 kt but the fuel burn is probably 3X and the bow tries to climb out of the water. You will see posts claiming “cruises at 8-10 kts” in ads but it is a lie. Set your sights on the 80-85 hp range and be happy. Anything bigger is a waste of time, money and space.

The Perkins 4-236 is a engine found in the Sundowner. There are two here in SE Alaska I know of with this engine, as it is the replacement engine in our Marben I spoke of.. I agree, TAD is a known supplier with a solid reputation. While a bit high in price, you do have assurances with their rebuilds. The engine itself is a engine that will go on forever, one will far outlast your boating hours. Simple engine to work on, nothing fancy, it is a tractor engine meant to be dependable with as few fancy add ons as possible. No computer, not tier "what ever". Air/fuel/and go.
By the way, our complete running takeout engine was later discovered by serial number to be a 2009 year, There was noting missing or having to be replaced. it has then and now, 60#oil pressure, runs like a top. Purchased from a fellow in Everett, Washington who had no knowledge or history of the engine,other than it was sold to him by a party he trusted.
He delivered to our Alaska Barge line for the full price of $1,000.00.Yep, a thousand bucks!!
We in turn sold our running takeout to a party in North Carolina!! Who paid $1200.00 in freight to ship from Ketchikan. We sold our engine to them for $600.00 and clearly advised that there needed to be a main seal replacement as it leaked. (A common issue with the 4-154.107 and 108 model of Perkins) All of this via craigslist which is preempted with a "BUYER BEWARE" warning. You have to do your due diligence to the best of available ability and sources when dealing at a distance.
