Jeez that is a beautiful area over there (the lake). Looks like the motor is pushing the boat along more than fast enough. Are your trailer lights submersible? I had to change mine out a couple of days ago because they leaked.
I tried putting the motor inside of a a can full of water like you said, and to my huge relief it worked, it started shooting water out the peehole. Whew... but I will keep an eye on it. Not sure what went wrong with the water mufflers, maybe the hose was not turned up enough. I really want to watch the weedeater project that you might take up so keep me posted, of course I am hoping that you make it an outboard instead of a charger. Regarding shipping my motor to you, I would have to find out how much that would be, I am going to let it sit for a bit because I dont want to mess with my boat yet. By the way, how much horsepower does a typical weedeater have?
Random photos below, including some fiberglass repair on the rear hull that I am trying...
Yes, That is a very atractive place to go boating, It is around 4 sq miles of lake, and is our public water supply. You cant go swimming or even touch the water, but They will let you drop a outboard in it and runn around dawn til dusk, Go figure.
My trailor lights are submercable, However, 1 is cracked and has been siliconed. I did leave the holes in the bottom there for drainage, The laws of pysics keep them dry. BUT, I do disconect them from the truck prior to launching anyway.
Yours is now the third motor I have ran accrost that does not spray water out the tattle tale when on muffs. I think this is also pysics demonstraighting the path of least resistance. I bet if you restricted water at the lower return port, It would make the tattle tale.
In any event, keep an eye on it, especialy if your impellor is old. Cant change it on the water if it dies so preventitive maintence is the way to go.
Right now, the weed eater is on the shelf awaiting my attention. It has only been ran to verify it works before putting it away. My plate is kinda full with yard work and other spring chores right now. Personly, I am leaning tward the generater prodject, I already have 2 outboards. Being able to make power wile at remote locations is something I could definitly make use of wile camping remote. However, It still might become a outboard for my friends raft. Time will tell,, If I find another weed eater, Ill make both, generater for me, Motor for him. If it does become a motor, there will be almost nothing to it. sharten the shaft, rebend it a little and make a mount for it and mount a prop. should only take a few hours if I go that way. I know it wont be a fast thing, but it shor beats paddling, especialy when your trying to move a raft. Weed eaters are generaly rated in CC not HP, I have no idea how many CC= a HP, But I am guesing me weed eater is between 1/2 and 1 1/2 HP. I know one thing,, weed eaters are HIgh RPM motors, so It should be able to adapt to either prodject.
Where were you repairing on your boat? that hole?? looks like that hole is a self bailer to me..
What is a self baler? We are not really plugging the hole, it was chipped on the bottom so we were fixing that. I noticed that the hole allows water in/out the lower hull-maybe to stablize the boat?
If you do make an outboard using the weedeater, what type of prop would you use, I only found props that spin about 1.5 times less than the engine rpm, yours would be direct drive (1-1 ratio) and like you said the motor would be probably higher rpm that most outboard motors.
I tried the muffs again today after using the boat (photos below), this time I cranked the hose up to full blast and water did come out the peehole, that was a relief. Having an idea about how many things can go wrong with these outboards I will always try to watch it closely. In fact today at 1/3 throttle, just before reaching plane it started to sound different, it went away after reaching plane and slower speeds. Hopefully the sound change was becuase of some type of transition between not on plane and getting on plane what do you think? Had a total blast today on the water, it brought back so many memories when my dad used to take me out on his yacht (33' silverton twin gas 300 hp engines) or his 16 footer/50 hp(we called it "the green boat"). We did not really take this boat on the open ocean, its a bit too small for that. Most boats should be at least 16' I think unless its a boston whaler then maybe a bit smaller. We launched at long beach harbor beacuse there two miles from the coast there is a break water jetty that runs parallel to the coast and is 8 miles long. It keeps the water calm for the cargo ships that come in. The only thing that seemed to go wrong was when I pulled the trailer out of the water, the right trailer light turn signal did not respond, althogh it did respond to the brake light. But I dont mind we had so much fun today. Photos below..
A self bailer is a device that lets water out of the boat without power. Most work on the diafram billows type principal of a 1 way port covered with a gasket letting water onyl travel out. They can work other ways.
As far as the weed eater, Its looking like its gonna be a generater ( sorry but I need a generater ) But, if I were to make the outboard, I would use standart MinKota electric prop. these props have a very slight pitch and should allow the weed eater to get up to full or near full RPM. I dont think the weed eater could turn a standart prop, at least not enough to be practical. Maybe Ill find another weed eater hehehe... There is some sort of clutch and possibly a gear box on this unit, so I am not sure about the 1 ta 1 thing.
as far as the noise you mentioned. You were probably cavitating, But I cant be sure. Scared of the big water huh? well if you dont feel you have enough boat under you by all means stay in safer water. However, dont underestimate your boat, those hard bottomed boats with inflatable bumpers are made for big water. Seen allot of boats like that Associated with the military, and I would say you have enough HP to cover the power base. Yeah I agree.There are allot that can go wrong with Outboards, or anything for that matter. I strongly encourage you to get to know that motor well, pack extra plugs and a few tools . I carry a can of starting fluid with me just in case, Its a terrible thing to do to a 2 cycle, but when stranded someplace, I would use it. ( fortunetly I never had to yet, but I still carry it )However, properly maintained and looked after you shouldnt have too many problems. Both my motors are old so I worry about them a little, but only a little. having the electric on my boat as a backup helps not worry about it too much.
the trailor light thing is probably a ground issue, Trailor lights are finiky sometimes. Could also be a bad bulb.
Its good to hear you are enjoying your boat ;). I have been out in mine several times lately. Oww, I was checking over my motor today, Under the hood looking for preventitive maintence things, chafing wires ect, and when I checked the throttle linkage I noticed something.. I noticed that it wasnt opening the throttle completely when twisted up too full throttle. I bet you I gained about 10% more movement after adjusting. GOing out tommorrow to see the difference. I was thinking the motor wasnt turning max RPM but without a Tack, I could only speculate. And I thought it was fast before hehehe. Cant wait to see it now that its gonna be getting 100% throttle at the carb. Im thinking of putting it in the river tommorrow, miles of mostly calm water and several like side marshes & stuff
