    Yam 150XB Flush Port

    So I finally graduated from an Evinrude to my current Yamaha on my new Tidewater. I keep the boat at a dry stack marina and one of their services is flushing the motor with Salt Away before they put it away for the day. Well, the last time I went out (still haven't hit 20 hours on the...

    Issues On Foggy Days...

    97 Evinrude 25HP # Cyl with Rope Start This has happened on more than one foggy day (3 that I can count) and very damp / cold nights. Motor starts up fine at the beginning of the day. I then make a few 15 - 20 minutes runs at WOT to different fishing spots, shut down the motor and fish for a...

    Is this ventilation or slippage?

    '96 25HP 3 Cyl. So a few weeks back I had my carbs completely Re-synced and had all linkages adjusted by an Evinrude dealer. They adjusted the timing back to exact specs (wasn't too far off) and replaced the plugs and plug wires. The motor runs with ZERO lean sneezes or backfires but the idle...

    New Issue for Me... cracked repair weld on trailer

    So, I was rewiring a loose connection when I found what looks to be a repair weld on top of the 2x3 beam that my axle springs mount to. This weld is now cracked all the way across the top and is now a split in said beam. This is a galvanized trailer so my question is can the repaired weld be...

    Possible to sync carbs on 25HP 3Cyl Evinrude

    Have been having a few intermittent issues with rough idle and I know that I have adjusted the low speed idle all three carbs to about the best they can be. I have seen a few videos and have watched Dangar Marine do a few carb syncs but all of them involve using a port on the intake manifold...

    Ideas with working on Outboard while in a Boat Slip

    I have recently moved my boat from my garage to a boat slip at a house on Galveston Bay in TX. I normally did most of my routine maintenance and minor repairs at home but I am hesitant to start taking things apart with the motor suspended over water. I've been trying to keep an eye out in the...

    Converting 25hp 3 cyl to 35hp

    I've searched a little and read through a pot back from 2004 where a 20hp was converted to a 30hp by simply switching the carbs out. I don't believe this was a 3cyl as mine is. ( 1996 E25RMEUR). My motor sits on a 16ft C.S and with three ppl plus fishing gear, I can plane out at 22mph. Flying...

    Fresh Water Flush

    Well, I was excited to get my boat a new home at a slip at a beach house with a lift this weekend! So excited that I actually didn't think through how I will flush my motor (salt water only) while in said slip. I normally use a flush barrel since I usually have to have water above my...

    Experience with "Tiny Tach"

    Trying to see if anyone has any experience with installing a "Tiny Tach"? I installed one on my 3 cyl 25HP just fine and at idle it gives me a pretty consistent reading. Issue I am having is at WOT. I'm pretty sure I am getting interference from my #2 or #3 plug wires because my reading jumps...

    Upgrading Axle

    Even though I only do this trip once a year; I tow my 16ft skiff from TX to FL and use my boat as storage for most of our gear so the dogs have some room to roam in the back of my 4Runner. The axle rating my trailer came with is 1000 lbs and the boat with motor and typical fishing gear is right...

    25HP Evinrude 3 Cyl was able to start while in gear

    So had the boat out a few days ago and was wrapping up a fishing spot. I went to start my motor and when I pulled the cord, I guess I did not have the throttle control completely in the Neutral position. The flywheel made a clicking sound when I was pulling it (1 pull mind you) which I'm sure...

    Experience with Installing Tach on 25hp 3cyl

    I’ve been wanting to install a tachometer on my motor (’96 Evinrude 25HP 3Cyl) but I’m not 100% certain of the potential wiring issues with my stator. I’ve also read about the “Tiny Tachs” and they look very simple to install but I’ve also heard you are pretty much limited to installing it on...

Recent history of motor: Carbs have been rebuilt within the last 60 days, all gaskets are new and replaced manifold gasket, replaced all fuel lines with new ones and new clamps within the last 4 months, new PowerPack in the last 4 months, carb idle...

    Starting issue "possbily" solved

    I hate starting a new thread but I may have landed on something: '97 Evinrude 25HP 3cyl with rope start. I was having issues getting the motor to turn over after rebuilding the carbs (the right way finally), inspecting all spark and ignition components and checking fuel supply. I probably...

    Trying to narrow down starting issues ('97 Evinrude 25HP 3cyl)

    Was wondering if anyone had ever experienced hard starting issues as a result of a clogged or obstructed exhaust port(s)...? I am still having intermittent issues with starting (rope start) this thing after trying virtually everything I have read and the advice I have been given. The other day...

    96 Evinrude 25hp 3cyl starting issues

    Well, for those that may remember my issues from a few months back, I finally got this thing running well (well, after a $800 power pack and re-working the head seals for a total of a little over $1k). Have had it out on several occasions and was even able to use it here in several Houston...

    Just got off the phone with the shop...

    1997 Evinrude 25HP 3Cyl Took it into the shop after trouble-shooting as much as I felt comfortable doing. Motor would not go WOT and would max out at less than 3000 RPM. Tried several things here with numerous recommendations from several members (thanks to those that gave me some input). Tech...

    '97 Evinrude 25hp 3Cyl

    Finally got my service manual today and have been reading through it like I'm looking for "lost treasure". I have had several issues trying to get my motor to WOT with no luck. I have gotten some great advice from several ppl here and it has really helped me learn a lot more about this motor...

    Where's the water coming from???

    1997 Evinrude 25HP 3 Cyl. Been doing a lot of work to this and the last major thing I did was inspect the flywheel key (motor will not get to WOT). After inspecting the key (was not sheared) and test running the motor, I have oil mixed with water slowly dripping from the upper exhaust next to...

    '97 Evinrude 25hp throttle issue

    So I have tried several things with this motor and can't seem to get it to open up beyond a fast idle speed. Motor starts on just about every first pull (rope start) and idles fine. I have cleaned the fuel lines, tank, disassembled all three carbs (and cleaned), checked compression (125, 124...
