The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
I'm at the lake for a week with my boat and I'm out of ideas as to what else to try to get my motor running right, I need some help...
The motor is an 1977 70hp Evinrude. It starts great, idles great, runs great at slow speed but bogs down on wide open throttle. With the fam in the boat it...
The tilt ram on my TnT is leaking fluid every time the motor is trimed/tilted, so I wanted to see if anyone has any good ideas how to fix it. The motor is a 1977 70hp Evinrude (70773s). The leak is coming from the seal at the top of the tilt cylinder where the rod exits (see pic).
The whole...
Ok guys, I need some advice. I just got back from the lake, it was my first trial run for my restoration/rebuild, and I'm having trouble with the motor. A little history, the motor is a 1977 70 hp Evinrude (70773s). I recently installed a new water pump and rebuild the carbs and replaced all...
I just finished putting my motor (1977 70hp Evinrude) back together after installing a new water pump and rebuilding the carbs. I put it on the muffs and fired it up and it seems to be running nice. After it had been running for a few minutes it started haveing gray foam around the prop and...
I am working on my first carb rebuild (70 hp 1977 Evinrude) and I have a question about float valve seat that is not addressed in the manual, are you supposed to put some kind of thread lock or sealant on the threads of the seat? I adjusted the seat screw to the height need to position the...
I'm getting ready to rebuild the carbs on my old Evinrude (70773s) and am in the process of making out my parts list and have a question. In the manual it says you need to replace the self locking screws that hold the air silencer base to the carbs (0323044 ? SCREW,BASE TO CARBURETOR (9 per...
It looks like I painted myself into a corner and I'm hoping that someone out there can help me come up with a solution to my latest stumbling block. I wanted to change the seating layout in my boat so I built a bench seat to go in front of the splash well (I will be building a back rest but...
I've had an interesting idea but I'm not sure it will work so I wanted to get some opinions from those who know about electrical wiring. I'm planning the new wiring for my restoration and I'm thinking about going with 2 sets of switches to keep the length of the wire runs as short as possible...
I am ready to reconnect the cap to the hull and I'm having a bit of a dilemma, the manufacture used rivets to make the connection but I'm having a hard time figuring out what size rivets to get. I'm pretty sure that the diameter is 3/16 but the length varies quite a bit depending on where you...
I just acquired a new Power Pilot remote control unit with a TnT switch and all the cables but it is missing the ignition key. Is it possible to get a replacement key and if so is there any way to tell what key it needs? The remote control on my Johnson uses a standard key that can be found at...
As I'm going through my (seemingly endless) list of things left to do on my boat I started thinking about the bilge. The question is should I paint the fiberglass in the bilge area and if so what is best to use. If I'm going to paint it I need to do it before I glass the new deck in.
So I...
I just did a compression test on my Evinrude but I can't find the compression specs anywhere in the OEM service manual. Here are the reading I got: top-115, middle-119, bottom-130. Does this sound OK??
Hi all, I am having some trouble with my TnT and I'm looking for some direction on how to troubleshoot/repair it. A little background, the TnT is off of a 1977 70hp Evinrude. It has the prestolite (3 wire) pump and uses one solenoid. I have the service manual for the outboard but since the TnT...
Hi All, After doing a lot reading here on the forum I've decided to take the plunge and start a project of my own. My project boat is a 1976 Sea Sprite Cougar 15 tri-hull with a 1977 70hp Evinrude outboard. This was my first boat, I used it for a couple of seasons then it was retired to the...
Hi all,
I am fairly new to outboard motors and I am having a problem with my motor that I don't know how to troubleshoot. The motor is a 1976 Johnson 35 hp. I am at a cottage with the boat in the water. The first time I took the boat out, it seemed to be running OK except that it would seem...
