Info on Pulse 186 --> max power, best match?

was reading through many topics, starting to wonder if there are any props available for this (I am reading about 245's with 30p. choppers....)

please advise..... Am I worried for nothing or is it too much?
 
i'm a big fan of big power, but that might be a little much for the boat. if you look through some old threads there was someone with a pulse with the same set up, i think it did around 90mph but i can't remember.

I've already done some digging around but haven't found a thread with a similar setup (yet) (that was why I'm asking)
i don't mind the 90MPH :D as long as the boat keeps controllable and doesn't start trying funny things on me (and less funny). Also I would appreciate it if the transom stays in place. (and if the lift will do the same that would be nice as well).

I have been offered the following engine
0hrs rebuilded Merc 2.5efi 280, 1:1,87, offshore midsection, 300 drag pistons.

Any idea if this amount of power works on a Pulse186 or that it simply is too much? (it's only 18,6ft..... (is it structurally strong enough :confused: and will it be any fun to drive?).

Any advice appreciated.

Hey Tom. I could be wrong, but I think "offshore midsection" means 25" or 30" shaft. I'd make sure you find out for sure. You are going to want a 20" shaft on the Pulse. As far as power goes, I'm pretty sure the Pulse can handle 280. Check your transom and make sure it's in good condition!

You are wrong. "Offshore mid" refers to a beefer mid section with offshore above water exhaust. The idea being that it is used offshore because it is loud and pisses many people off if you run it on an inland lake. Typically a 20" mid on the 280's. Personally, for recreational use I'd stay away from a 280. They need to be rebuilt every 100-150hrs.

Always good to know when you are wrong. :banana:
 
Ya for normal where and tear I have not heard alot of good things about the 260s or 280s. I know you can look on scream and fly and see alot that are new or rebuilt, must be a reason for that.:bigthumb: Aaron

The 260's and 280's are actually very good nmotors if you use them in the correct application for which they were built. The problem is people think that they should give as long of a life as a bone stock 150 and forget that these motors are consumer race motors. It would be like taking a motor built for NASCAR and expecting the longevity of a motor that comes in their station wagon. It doesn't happen.

If you run good oil and fuel and warm them up properly you can expect 100-150hrs before rebuilds. (Rings, seals, & bearings) Some guys run them longer but you run a risk of ruining the powerhead because of ring wear etc. On a standard production motor you can easily see 500 - 1000hrs between rebuilds.

To me putting one of these motors on a Pulsare or Pulse is silly in my opinion. Buy a nice Opti or EFI and get the run quality and life expectancy out of your investment. It won't be much slower, if at all, either.
 
I guess you could say Im more into the 500-1000hr motors. Im really not into tearing it down after a season or two, nor could I affrod to do that. I guess I will just stick with my yamaha it was still runing great after 20 years. I sent the power head off to RAY NEUDECKER a few weeks ago, so now ill I have my own 260hp but a yamaha version.

My pulse 186 hard deck with 6" of set back and a 175 merc ran 64-65 gps with 3 adults. Guessing a few more mph by myself. I had a 23 tempest plus turning 5900-6000. Go for 200+ horses, have fun, and good luck
