Re: Need to PROP. HELP ME .. PLZ
You should find the prop size on the barrel or under the prop nut.
Prop diameter will help a little but won't mean much.A prop shop can measure pitch for you.As I understand it its a twin are you running both engines?
Both have good compression and well tuned? throttles opening all the way?
Bottom clean?Could boat be holding water in foam under the floor boards?
Is the timing advancing as it should?
Yes. i run both of my Engine. is it possible to run just one engine and still go forward. last time i try i was going side way.
The bottom of the boat is clean...
JEZZZ i have never thought that will cuz problem.. it was raining here in san diego. 2 or 3 days none stop. the cabin was flooded. no electrical was damage just wet. i try everything. and everything seems dry.
but there is that little hole under the steps toward the cabin where it has a CAP which allow me to open. and it has water. it has Hoses around that little area. which i assume its normal to have water in that area. because there is hoses which lead to outside the boat. but no pump. i will put a small pump later in that future..
but as for that little water. is that a big problem of why my boat seems so slow. maybe it add a little bit of wait. but i just dont see why it will effect the speed..
as for Engine Timing. I time the Engine as the Book said.. 10*Degree BTDC. . its not advance.. engine idle around 700 RPM. but most of the time it dont usually stay at that RPM it jumps around 850 to 700 RPM from time to time.
throttles open all the way.. I dont know what you mean by this. but i assume the Carburetor throttles open all the way just fine. and if you mean if i open the throttles all the way open and if the engine still run without a problem then yes. it does work properly..
Carburetor is not well tuned. it runs and stay alive. and keeps its lower RPM. and when i push the PEDAL to the FLOOR and CLOSE it. ENGINE STAY Alive. ..
NO backfire.. sound preaty clean..
i will video the engine running when i have time. so you guys could see. i will post it on youtube and post link here..
but for the PROP
