How do i break-in and tune?
I just bought a used apache 56 with a zenoah 260, The guy that sold it to me said this was his first gas boat and he was only halfway breaking in the engine than quit. He said all i have to do is run another 2 tanks of gas threw it for it to be fully breakin in. How do i finish breakin in the engine? After that how do i tune the high and low needle?

RE: How do i break-in and tune?
Hi, got my first zen a month ago, the instructions said it didn't need any special break in procedure so I just fueled it and went steady for a couple of hours.
Seems fine at the moment. Not sure if this is right just my (limited) experience.
As it relys on a piston ring to make a gas tight seal in the combustion chamber instead of an interference fit like in a nitro engine it shouldn't need any special break in.

just make sure you do a few laps at moderate speed to let the engine warm up before you hit WOT. make sure you have water flow through the head, manifold & pipe at all times too. that's all you need to do.

So thats all i got to do to tune the engine, set the needls like that? Would that be good enough for everyday running or do i have to adjust when the temp outside changes? I am always gonna run it in saltwater, so what am i supposed to do after i run the boat in saltwater?

rinse with fresh water, thru all the lines and rinse inside and outside. Then spray entire motor with wd40, remove spark plug and wd40 the inside also and give it a few cranks. After that keep cranking it upside down to drain wd40 and any water that may be in motor, give it a quick spray of wd40 again replace plug and you done.

I also live on the beaches. I have a hose attachment in my garden hose that I use to flush, or use to adjust my engines.
Check out post #314 in the "AquaCraft Rio 51 anybody?" thread (page 13??). I would give a link directly, but something wrong w/ site now and I can't post pictures, or anything else other than replies.

RE: How do i break-in and tune?
I would be running this apache boat aboat 40 to 50 miles offshore on my 115 feet shrimpboat when i am anchored. Whats the recomended needle setting for the zenoah 260 for the engine to always be running so it wouldnt shut off because of it being to lean or rich. Because if it goes dead out in sea then i would have to crank up both of my caterpiller v12 diesel engine and winch up my 700lb anchore on my shrimpboat to go get the apache.
Do i need to keep spare srapk plugs handy? What kind of spark plugs and oil do i need for it?

Get used to it.....it WILL stall at some point in time. There is no "Magic" setting for the carb to prevent stalling. Too many factors....even water getting in the carb AFTER you find your perfect setting. Go a little rich if anything if stalling is what your worried about. May lose some top end, but will be less likely to shut down on you.

fishing pole and tennis ball works for in close
,attach some strong cord through the ball and tie your lijne to it and cast,i use the butt end of a sea rod(beach caster).If you go far out then i suggest buying a small dinghy and some oars or a small motor.

RE: How do i break-in and tune?
What kind of oil does it have to be? Could i get the spark plug at any car hardware store? I had received the apache today and the old owner had remove all of the fuel line and all the water line and i dont have any idea where the lines goes. Theres 3 line where the water goes out of the hull, 2 on the exaust pipe, 2 on the engine, 1 for the water pickup, 1 for the engine by the exhaust, 1 for the ruder and 3 from the water pump. Does anyone have any clear pics of where the lines goes to?
