Default Perkins Marine Diesels

I have a 1969 27' Bertram style hull with twin rebuilt 350 chevy engines with 2 barril carbs, sitting for lack of use. After trying to sell her for a couple of years at a 50% loss ($12k), I am condering repowering her with deisels.
I am not willing to spend $40K+ for twin Yanmars or Volvos on this old hull, but see that new Perkins 4cyl are going for less than $5K apiece, and 6 cyl are about $8500 apiece here in Mexico.
These are the old english style non turbo low horpower engines that I have run in trucks, but I have never heard any input as to marine applications. My fishing grounds are only 6-20 miles away from port and if I make up to 15 knots on autopilot I will be happy, as I also have a 40 mph 19' Cape Horn to bounce around in too.
Waddayall tink???

If your boat is really like a Bertram with a deep Vee then you will not even get her on plane with 4 cyl Perkins. Those engines are made for sailboat aux power and displacement hulls like trawlers.

Perkins was bought by Cat so parts are easy to come by and they are good motors.

I'd go with the I-6 naturals. They'll last forever.

I have a 1993 Perkins 6-354 240hp. Good motor. Parts are fouly expensive.

I don't think there are any new 240 HP diesels for sale for 5-8 thousand dollars. What the original post asked was whether those small engines he is considering would be suitable for a Bertram-like boat. The answer is no. That boat needs at least 450-500 HP to run right if it's anything like a Bertram.

100 HP can push a 36' trawler to displacement speed but you are not going to fair well with a planing hull on a boat like he describes with even twin 100-150 HP diesels.

Since your fishing grounds are only 6 - 20 miles from port, it sounds like your best bet is repowering with gas engines. You can buy a whole lotta gas for the price difference between gas and diesel engines.

Sleeper,
The 4cyl are listed at 65 hp, and the 6's will go about 90 hp is memory serves me right.
my boat with 2 300 hp chevys will top out at 31mph, but chugs the gas even when just using 1 engine to troll with.
Local charter boats only get 250-350 per day, so $150 for gas also makes this a no go in my area.
Somebody says that Cat bought em out, so I willl reconfirm my prices, but these were real 15 months ago when I last priced them here in Mexico, and a 6 cyl rebuild kit with pistons, rings, valves etc was under $450 dlls, so it may be a local market thing that I can take advantage of.

I'll confirm that a pair of small 4 cyl anything is just about useless in a hull remotely resembling a Bertram. There is a North Coast 26 here with a pair of Perkins 135hp. What a dog! The best it can do is ride around with its nose up in the air & its a$$ dragging.

Take a look see at http://www.cummins.com for a dealer in your area of Mexico. Then pick out the model that best suits you and contact that dealer or distributor. There are plenty of re-built Cummins engines available. That's where I got mine.
