The 280 with drag electrics would be a fun motor.......I think the power level would fit into the "big" category you are looking for.....

im looking for somthing like that but also somthing on the "enrty class mechanic" levle too supthin easy to work on and play with EASY truble shout kida thing (simple) and would a sleved moter be beter then non sleved and when all thes mods are done to a moter can it still run on regular fule or is it now race fule
cus really this is more for a 12 year old boy more then it is for me BUT HE wont be drivin it! he renches with me on my sleds and he was the one who actuly got me on to S&F!

A stock 280 would be a good choice, just gas and go......fresh gas and spark plugs everynow and then, change gear lube...normal stuff........:thumbsup:

i have a 09 hpdi 300 yami that i run on my 20 ft fishin boat but i want supthing i can tune that hpdi lol well i dont know what im looking at! and for it to be a cheaper build project thrue time

The 2.5's are all very simple engine's. If you want bare bones, then you want a carb 2.5

Regardless there are electronics involved in both which can be a huge mind boggle when trying to trouble shoot a problem.

The 280 jay talks about will most likely run just fine on pump gas min 92octane, with race heads on it you would need to run higher octane which would be atainable using aces additives, a product Jay swears by.

What kinda boat are you putting this on? a 280 with a alternator kit makes a great lake running motor, while still being able to listen to tunes all day long.

While they are no the cheapest, there are lots of spare parts and lots off knowledge available on this forum for any of the 2.5 high perf engines.

The only wa i wouldnt run a 2.5 on a small boat. Is if i had the money to buy a brand new Full Throttle Power STV Euro and throuw either a 250 or 300xs on the back for lake running

Go with Jay's engine and order to fit your needs. You simply will not go wrong. There is no comparison power to weight to the 2.5 (depending on your application), bar none.

IMHO the 2.5 Horn Motors (even the 280's) are the simplest of today's motors to work on. Think about it, racers want to be able to get at things quickly and friendly.

Open up an Opti, and with my temper, I'd push it into the lake.
