    1998 Evinrude 200 replacement sleeve question

    I have a motor I bought cheap, disassembled and the block is at the machine shop being inspected. Two holes have turned sleeves, and one was tore up pretty good. If this motor comes together (and not parted) I will look at the water jacket modification. The Shop bored out the banged up sleeve...

    Tips/hack for seperating 200hp Powerhead from adapter?

    Starting my Project 1998 200hp Rebuild. Got it for a couple hundred bucks--pretty good shape minus 1 cyl. I've done enough V4's to know what I'm doing seperating the PH. But this is my 1st V6..Heavy and awkward for sure! Everything is out (all bolts came out easily) that needs to be out. I have...

    1989 Evin 200 looper, may purchase for rework

    Guy in nearby town has this 25" 1998 200 looper motor for sale. Wants 500. Havent looked at it yet but he seems knowledgable and did inspectors it. He states one hole is scuffed. When he took head off, appears rod bolts came loose/broke as the piston was able to come out. This would be a...

    Piston cleaning, too clean??

    I've cleaned a set of std crossflow 115hp pistons. soaked them for days in Berrymans (the not-so-toxic) Walmart can. Over a week I got them all clean, mostly by painstakenly and slowly rubbing, and picking the carbon off with nylon brushes and picks. Lots of work. Man, they are clean...Super...

    Compression testing of PowerHead on Bench?

    Am I able to spin my 115 powerhead on my workbench safely, to test compression? Once my rings arrive, I'll finish putting this together. I usually mount it up to the rest of the leg (but all that is outside in the cold) to properly test. I thought if I just put the starter and selenoid on, I...

    do the 150 crossflows (1985) have a diff steering setup from v4's?

    Ive got a pair of 1985 150's recently and just beginning to mess with them a bit. I need to swap in a TNT motor to lower one so I can get it onto a stand to run it. But I noticed each of these has steering Tilt tubes, that are blocked inside, meaning they appear that neither had a steering...

    Please update with resolutions or update open threads-help others.

    I hope I'm not mis-speaking here!...And I don't mean to offend If I do. But Nothing is more frustrating (well I guess there really is now that I think about it), than to follow a thread that some very kind people have helped on...only to find it open and never resolved or even updated! The OP...

    Ive read the related threads on these not turning off with the switch, or direct grounding of of the Yellow/black kill line. I have all the switch and Remote/cable pin-out diagrams and am familiar with what line does what. In testing my new to me 150 on a stand, with remote and wired-up key...

    Purchased 2 complete 1985 150's for 400.00

    I'm so cheap, hate spending money.. I have several older v4 crossflows, but have been looking for a buildable v6. Finally a local guy was selling 2. Both are pretty clean, 1 was a freshwater motor, other Salt. He ran one, when the TNT motor went, he found a complete 2nd motor supposedly running...

    Am I charging? Mixed results with swapped Regulator

    Got a 1984 PHead on '93 Lower...Had an issue with Tach Jumping, and weak batterys..originally Volt meter and fishfinder would show up to 16v when Tach was jumping, and 12.5v solid when tach sat short periods at Zero--this was on the water and only above 3k rpm. So, did my research.....Found I...

    Are VRO and VRO2 pumps interchangeable between years if Mixing?

    Here's why I ask....Had a fuel delivery problem on 1984 115 (rebuilt Powerhead). It would come to plane, then die out. A couple seconds at idle and I could plane again for 15seconds.........I know it was fuel, So I swapped the VRO and did a complete carb rebuild. Test run ran real good...

For the issue, just tonight I swapped the VRO/Fuel pump unit with another (I mix), and did a complete carb rebuild properly( Berrymans, wire and air). Will test tomorrow. THE...
