    One magnet vs Two magnets in 1975 25 HP Johnson flywheel?

    I've had my outboard in the shop for the last two weeks that's new to me getting a tune up and a one over. One of the things my mechanic noticed was that the old flywheel on it was cracked so he had me order a new one. My motor is a 25 HP Johnson model number 25R75B, the part number for the...

    1975 25 HP Johnson Trim Tilt

    Hi, I'm bringing my 25 HP Johnson to a mechanic next week to get some work done on it. At this point I'm unable to trim the motor up because some of the parts are missing off the motor. The mechanic tried to caution me that these parts can be very expensive to replace, but most of the parts on...

    1975 25 HP Johnson Cam Roller Not Meeting Cam

    Just bought this motor a month ago in working condition. Did a stupid thing and forgot to strap down back of the boat and drove a few miles with it like that on the highway with the back of the boat bouncing around before I realized what was going on. Mind you it wasn't jumping up and down in...

    8 inch tires not highway legal right?

    I bought a new to me boat w/ accompanying trailer that came w/ 8 inch tires recently. From previous experience with a previous harbor freight trailer I knew 8 inch tires where not highway legal, so on that trailer I took off the fenders and replaced them with 12 inch rims w/ tires. Even the...

    Bay fishing in a boat this size?

    Figured I'd make this topic just out of curiosity. I'll soon be the owner of a 14ft smoker craft with a 25 HP Johnson. It's got a 5' 3" beam. I usually make 2-3 trips down to wildwood nj during the summer and I've rented out some carolina skiffs that aren't to bigger then my soon to be aluminum...

    1975 25 HP Johnson Conversion to 35 HP?

    So I was curious to see if a 1975 25 HP Johnson could be converted to a 35 HP by changing out the intake manifold and carb since that can be done with later models in the 80s. The 1975 series doesn't have a 35 HP model, but the 1976 series DOES have a 35 HP model. I've seen topics here that the...

    Information on 1975 25 HP Johnson?

    I'm looking at a 25 HP Johnson that the dealer has advertised as a 1985. Looking online based on the decals and the green lower unit I've identified it as a 1975. I own a 78 9.9 HP evinrude and from what I know from reading on Leeroys Ramblings about the 9.9/15 HP series, motors that where made...

    Generator for charging trolling motor battery/fish finder battery while camping?

    I'm going camping up in the adks in a month. I need something to charge my 2 trolling motor batteries during the day since I usually fish the morning and evening bite and chill out with the girlfriend during the day. I've got two12v 100amp deep cycle marine batteries, and a little 12v 9amp...

    Too much "deadrise"?

    So I currently own a 9.9 evinrude with this 12 ft rowboat. I've put a lot of work into the motor and I still can't get over 10mph. There are many videos on youtube of guys getting to 20-25mph with the same motor on 12 ft boats. Here is one such video https://youtu.be/M_OZ4Qa7H9g I've been...

    78 9.9 evine slow @ WOT

    Ive pretty much thrown ridiculous amounts of money at this thing and still can't find a mechanic who will work on it and address the issue that it only gets to 10mph at WOT. It has a 15 hp carb in it. I know the carbs cam roller is synched properly. It has 93 psi on both cylinders. I don't...

    9.9 Cam roller synch

    So Im doing a carb clean on a 9.9 evinrude. When I put the thing back together I need to synch the cam roller with the cam. The guide talks about hooking some sort of alligator clip onto the starboard side of the carb so that when it just starts to move, the cam roller should align with the...

    Blown Head Gasket?

    Alright so I picked up a 1978 9.9 HP evinrude this past winter and when I checked it it had 100 PSI on the top cylinder and 97 on the bottom. Ran fine in a barrel. Took it out in april and it overheated, but didn't sieze up. Checked the combustion chambers and I didn't see any scoring. Rechecked...

    Correct Carb Repair Kit...?

    I recently picked up a 9.9 hp evinrude with a 15 HP carb. . .who knows what year the carb is. I found this carb kit replaced the carb for a 9.9 HP 78 and most other years.... http://shop.evinrude.com/products/552632/Outboard__-_Carburetor_kits?p=398453 That contained a new float, new welsh...

    78 9.9/15 HP Evinrude Coil

    I recently purchased a '78 9.9 HP Evinrude with a 15 HP carb. It's my understanding the 9.9 and 15 HP motors of those years where the same exact engines with different carbs. I bought the engine back in January and it started just fine. Did all the basic checks; compression was 100 on the top...

    Seats effecting boat stability?

    So I bought a 12ft v-hull last spring that came with two boat seats on stationary swivel mounts. Ive found that because Im 4-5 inches higher in the boat it effects the stability somewhat. Its not as unstable as a kayak but the boat is way more stable when I lose the chairs and sit on the...

    What should I look for before purchasing this Johnson 9.9 HP outboard?

    So I'm kind of of new to the world of small outboards, and boating in general. I own a small 5hp seaking, and that has it's own gas tank attached. When I bought the motor I made sure the lower unit wasn't seized just by seeing if the propeller moved around. I had the guy start the engine and...

    Max HP for this 12' V-hull?

    This is my 12' V Hull I bought off Craigslist in the hudson valley area last spring. Took it up to the adks with a 5hp outboard. Thinking of picking up a 2 stroke 10hp outboard for it though. It doesn't have the hp rating on the HIN # plate. . . What do you guys think? Also the seats in the...
