    1987 Larson DC-215 restoration

    Hello all, I have a 1987 Larson Delta Cruiser 215, and it is a beautiful but old boat. The goal with this boat is to restore it and give it to my dad when he retires. There are a lot of things that I'd like to repair, but I'm having trouble finding restoration parts. The biggest thing that I'm...

    No spark

    The boat I am working on is a 1989 mercruiser alpha one with a 5.7 and thunderbolt iv ignition. I am at WITS END with this thing. I have had issue after issue and every time I fix one another pops up. Today's issue:no spark. I did a compression test before I left and stupid me forgot to ground...

    The clunk continues (and other issues)

    So, I'll start off with saying this is an 89 Mercruiser 305 with a 350 short block. I've got 3 issues to tackle. I chose to put them all in the same post so that I didn't clutter up the form with a bunch of posts all at once. First, I believe I have a vapor lock issue. The boat starts fine cold...

    How to make engine A LITTLE louder

    I'll start by saying I DO NOT want to do a thru-hull exhaust. Ear drums aren't cheap and everyone I'm sharing the water with deserves to keep theirs in tact. That being said, I can't hear my engine. At all! I can barely tell it's running at idle, I only hear the bubbles from the rear. I built a...

    Fuel delivery issues

    So a few months back, I purchased a 1989 Larson DC215 with a mercruiser 305. The block was cracked, so I picked up a 350 short block, changed rings and bearings, and put all of the 305 gear back on it. The tank was full when I purchased it, and I'd estimate the fuel in the tank to be about two...

    Noises coming from transom area/outdrive

    I just bought an '89 Larson 21' with a GM 305 mercruiser in it. The block was cracked when I bought it, and I built a 350 to put in it's place. Just got the motor in and started yesterday. Engine runs great, but I hear a noise around 1500-2000 rpm coming from somewhere behind the engine. Best...

    Big Twin 40 HP bogs at high rpms, carburetor is clean!

    So thanks to a lot of patience and help from you guys on the forum, I have my 1963 big Twin up and running, sort of. I got it all together and took it out on my boat (longshaft transom) because the carpet on the boat I am restoring had not yet dried. The engine started fine, but it vibrated...

    1963 Evinrude big twin starting issues

    I decided to start a new thread for a new issue. I just rebuilt the big twin and tonight I started it for the first time. I set it in a drum of water and I began with choke on, zero throttle and cranked and cranked it in 5-8 second spurts. It sounded like it was running with the starter motor...

    1963 Evinrude Big Twin with no spark

    Hello all, I am new to the forum and I am currently in the process of building my first outboard. I have been building engines for cars, bikes, and all sorts of things for 7 years now, but I've never done an outboard. I picked up this project from a friend as this was my grandpa's old boat that...
