    115hp 2 stroke on a Stracraft Mariner 21 ft?

    Thanks for the feedback guys. It's a '76 starcraft. Sounds like 115hp isn't a bad bet especially if I can find one at a reasonable price. Just trying to get up and running again this year.

    115hp 2 stroke on a Stracraft Mariner 21 ft?

    I'm shopping for a new motor to put on my boat, the maximum it's rated for is 140hp. There are very few motors in my market used in the 135 - 140hp range. I wanted to get some feedback from folks on if a 115hp 2 stroke would be too underpowered for this boat? With my old 135hp blackmax i got...

    Starcraft Mariner '76 21 ft Splashwell modification questions

    This is great feedback and makes a lot of sense! I definitely feel like I have a path forward here, now I need to fabricate the new splash well.

    Starcraft Mariner '76 21 ft Splashwell modification questions

    Here are some more examples I've found. This all just leads me back to - anything should be possible here - i just need to ensure things are properly supported. But i'm really looking for experience from those that have refabricated splash wells to maximize space or reamagine their boat layout

    Starcraft Mariner '76 21 ft Splashwell modification questions

    That's a cool setup! This has been my curiosity. If the splash well is truly in place to support the high walls, could i run a vertical support like the other rib supports i took pictures of, and then connect that support into a lateral support that is lower. I'm really not sure, but at a...

    Starcraft Mariner '76 21 ft Splashwell modification questions

    I've done a lot of digging around the iBoats forums, and internet more broadly to really comb through what people have done regarding the giant splashwells on these older boats. I also know a lot of people's position on this subject: it's structural, leave it like it is - if you don't like it...

    1976 Starcraft Mariner 21' Layout Changes? (v2)

    Oh, I could go above 4000, but that's when it ran rough, so i usually cruised between 4000-4500. So to your point it could have simply had the wrong prop. However, all that aside, the motor is toast, a rebuild quote at 4-5k on a motor that's worth 1.5k on a good day just doesn't appeal to me...

    1976 Starcraft Mariner 21' Layout Changes? (v2)

    Truthfully running over 4000rpm it started to sound labored / bad. probably a sign of things that i should have taken more seriously before the piston ring blew. And regarding 2 stroke vs 4 stroke. i'm looking for more fuel economy, and a more modern motor over all. i'm ok losing the 2 stroke...

    1976 Starcraft Mariner 21' Layout Changes? (v2)

    Sounds like we are thinking along the same lines! I'm open regarding which floor/deck material to work with, but i'm certainly leaning toward aluminum if I can source it well. It would help keep weight down (and top speed up). Granted I rarely run over 4000 RPM, but I also know moving to a 4...

    1976 Starcraft Mariner 21' Layout Changes? (v2)

    That's awesome! I feel like I know those baits, I too run a small fishing company focused on muskies. And I too am totally ignored at the ramps in my current tin bucket. Not a bad thing honestly.

    Fair points, the kids won't be small forever that's for sure! All good points and suggestions here, thank you for your feedback you've given me plenty to consider.

    1976 Starcraft Mariner 21' Layout Changes? (v2)

    Agree on the payments, not looking for the kind of debt a new boat would require. And nobody out there makes a deep v single console that seems easy to find. I took my layout from the lund musky pro v. Thanks for your feedback! I'm excited to build the concept. My main concerns are ensuring...

    1976 Starcraft Mariner 21' Layout Changes? (v2)

    That's an interesting alternative I hadn't considered. I do feel like I need a casting platform of some sort, as casting without any elevation in this boat is a bit challenging when Musky fishing. But moving to a front only casting deck and making it huge is interesting.

    1976 Starcraft Mariner 21' Layout Changes? (v2)

    Hello Team Starcraft! I've been here before but it's been a long while, back in 2016 I bought an old (76) Starcraft Mariner (21). While the transom was certainly worse for the ware, the rest of the boat was in great shape, so I pulled the trigger and took on the project. The transom project was...

    How to delete oil injection on 135hp Merc Blackmax

    Hi guys, I've read that many people delete their oil injection on these engines, and mine is acting up pretty badly, I've had some issues with it before, and I'm ready to be done with the oil injection and start mixing my gas. Does anyone know of, or can provide a good walk through of how to...

    Mercury Black Max not going above 2000 rpms

    The motor is a 135 merc black max, late 80s or early 90s, not positive. I'm hoping to get some feedback on what may be going on with my motor. This weekend was the first time getting her on the water since last year. Last year she was a hard starter at times, but no real problems so to speak...

    Broken mystery piece in Merc Blackmax 135

    I'm not sure what this piece is, but when I took the hood off the motor I noted it was borken, and looked like it snapped off, In one of the pictures you can see me hold the piece that was attached. Could anyone tell me what this is, and what i should do to fix it, also, is it critically...

    Best Bimini Top for Starcraft Mariner 21 footer?

    The boat has all the hardware for it, but I'm unsure what kind of top to buy for this boat, any hints, or know what anyone else has used in the past? Thanks.

    Wise Blast off bench seat installation examples

    Hey guys, I ordered the wise blast bench seat to install in the rear seating area of my boat, I'm looking around to see if there are any examples or installs that people have done with this model. It's sold here on iboats as well as many other places, so hoping this is a somewhat common item...
