HPDI VS 4 strokes

[peter devine]

I own a 1997 272 sailfish with T225 yamaha ox's (thirsty little buggers) 1 Considering better fuel economy
2 thinking about T200's I cruise around 3600 rpm@25knts now and thats fine with me
3 with the T225 my scuppers are below the waterline and I dont like this. This year in Southern New England scuppers are full of barnacles.

any suggestions from people with simular set up?

Peter, I have a 1992 sailfish with twin 200 HPDI's. IMO they are economical and my scuppers are well above the waterline. Just from memory I was running at 4800rpm the other day and the fuel meter said 22 GPM.

F200's and F225's (same block) weigh more than OX's or HPDI's.

I have owned both 4 strokes (current) and HPDI. Both are great engines. Keep away form the 300 HPDI as they had a history of trouble. I personally like the quieter low end and the more pleasing high end noise level of the 4 stroke. The HPDI's was better for getting our the hole if than a single F225 however I am now running 2 F225 and the power is what I consider perfect for my Sailfish.
Good Luck

200 HPDI was - IMO - the best motor Yamaha made....I'd buy another in a heartbeat. In fact, if I could find a good used 150 HPDI, I'd consider repowering the 180.

The 200 HPDI is going to have just as much if not more HP than the F225. Definitely more torque.

I guess I asked the wrong question.
My main objective is to get the most fuel efficient engines for my set up
I think I am around 1 NM per gal @ 3600 rpm. Does this sound about right with a 272 sailfish not heavy loaded with 3 guys average in weight.

This limits me from the cannon fishing unless I bring portable tanks. The cannon run from Bristol RI is around 85 miles 1 way

My Sailfish has 220 gallon capacity. I get a bit better mileage than quoted - I would guess 1.2 to 1.5 miles per gallon.
If the question was on HPDIs , they were very fuel efficient when I went from a 1995 200 Johnson to a 2002 200 HPDI and the fuel savings was probably 30-40 percent!

Thanks legend
That was what I was looking for. Trying to extend my range. :lol:

I concure with the HPDI savings on my 272, and they are lighter so there is no scupper below the water line issues. I was able to find a pair of 200 HPDI engines, one with 0 hours on a complete new Yamaha remanufactured engine and one engine with 121 hours. Including removal of the old OX66 motors and full rigging of the new engines my cost was under $13000.00. The 272 will hit 41 mph at wot with the new motors with 13.75X 19 props. I am, at 4200rpm getting about 1.3 mpg vs .9 mpg with the old motors and they start so much better than the carb mators

The 272 is close to the same weight as my 265-
I bet with twin 200 HPDI's (that is what I have) you will see 1.5 mpg loaded - and could see higher when running light-
I can get nearly 1.8 if very light!
Good luck!
