Sorry to hear of your blown motor. Was looking forward to seeing you in Tampa. Might be worth doing an autopsy/careful teardown to learn cause of failure. Sounds like maybe a rod bearing? Corrosion of bearing journals can become a problem on 2-strokes if motor sits a long time w/o being fogged.

Merc's fit - probably more of them on SeaCrafts than anything else! Don't know if mounting hole pattern is same as yours. Contact Fr. Frank - he's a Merc guru and I believe close to you. A rebuilt powerhead is also another, and possibly cheaper, option if lower unit is in good shape.

its a 97 merc 135 v6 i heard u have to be careful with the 135,s i guess there wasa bad batch but for 800.00 i aint complaining

If your transom is unmodified, the '97 20" 135 Merc will be a good choice. I run a '92 20" 150 Merc, reman'd in '02, that actually produces close to 200 hp. I used to run a 120hp Chrysler (yes, a Chrysler), and it was adequate.

I moved up to the 150 because I bartered for it. I was actually looking for a mid-80's 115 or 140 Mercury inline 6 when I found the 150.

Tear down the motor . . . and see what happened. If you need any 2.0L parts just holler. I'm parting out a mid 90's 2.0L right now. The crank is on ebay. I have nice set of heads and some pistons . . . + the 150 carbs. Also have a long 175 XRi Tuner and a short 200 bell tuner.

I'm pretty sure that the 135 and 150 are ported the same. Don't throw that old motor away . . . It's a great motor for sparparts or rebuild.

Here's number for parts or help even used stuff, you never know what they may have laying around. American Marine in Tarpon Springs 727 938 9796 they are Classic SeaCraft friendly and are set up to ship parts. Mario is the guy doing the 300 on a 23.
