Dear, Everyone

I am looking into buy a Predator 212cc for a boat motor and have a few questions

  • The engine I am looking to buy comes off of a used PREDATOR 2 in., 212cc Gasoline Engine Semi-Trash Water Pump, I have heard that water pump engines have a threaded shaft and not one with a crank end with keyway, is this true for predators pumps?

  • Since its for a boat motor its not going to have something to seriously slow the engine when I rev it. would no Governor be a good idea?

  • I plan to keep the stock internals, aftermarket carb and exhaust, $25 amazon aluminum flywheel, no oil sensor and no governor and 18 pound valve springs, does this sound fine for stock internals?

  • I plan to add a pulse pump, does anyone know how much they pull? It would most likely be pulling gas through a 3 or 4 foot gas hose.

Thank Ya'll

Nash, I appreciate your well thought-out posts. It is obvious you are doing some research and thinking about your project. I am in agreement with the guys who've posted above. Some of them, Triley for example, have done a lot of the modifications you have been looking at over the years.

I would echo the sentiments that say to use it stock at first. Figure out the "boat" stuff, and get that all working with a stock engine. You only have to remove the oil switch wiring at first. Then just get a feel for what you would like to do. No pump or fuel tank issues, just run the thing and see.

Definitely, once you get the nautical stuff set up, you'd want to get more power. It's easy to do, lots and lots of advice on here about making power with reliability, fuel pumping, etc.

Just more advice from an old person. (Never thought I'd be an old person) Or, just ignore us and do your own thing. That is OK too. I know I've done it that way. It costs more, this "learning curve" but there is some advice out there that is not good advice, and I've found a lot of us old farts like to talk and talk and show the world how smart we are. Pretty much like I did in this post. :) The advice you get in this forum is generally the best advice you are going to get- there are other places, but not many.

If you were my son, or grandson, and you said you were going to install a $25 Amazon flywheel on anything, I would not send you any more birthday cards. (And get off my lawn)

For the price of a predator, I'd buy a new one so you know what you're working with from the start. I would use the motor with the governor and zero modification to start. I think straight out of the box it will preform well.
Nothing is going to suck worse than starting with a used motor and have it fail halfway into your trip.

Yeah, or in the middle of Mobile Bay

LOL, disowned for cheap Chinesium, I am not trying to say how great I am but, all of my projects normally get the OEM or OE manufacturer part treatment, like my Tecumseh, and other car projects. This Predator was gonna get the China part treatment, but ill refrain,

  • You all have great points I am going to leave the engine stock for the start run

  • After I get the boat stuff figured out I am going to get the the fuel pump figured out as I am going to run an external tank,
  • However I am going to buy a China exhaust and muffler and weld it to go straight out the back.

  • Since, for the most part I am not going to go the China route, but it do want to buy two things the exhaust which is gonna be from amazon and possibly a carb, where can I buy a good cheap one? Or is the stock carb good enough?

  • If not a neighbor gave me what seems to be for a clone engine and its a big air filter so I might just use that but I don't know. As I don't want air filter that's gonna let in a ton of water if the boats splashing a ton, if its raining or if its misty out on the water. (I say this for I plan on using the boat in saltwater as well.)

  • Speaking of carb I am going to be running a minibike throttle grip can I use the original throttle linkage for the 212cc or do I need an aftermarket or minibike style one like on Tecumseh motors?
Again, Thank you all for the answers and advice.
