    8.7 Volts at the Coil

    I think I'll check the main engine grounds and the connections at the perko switch. I agree something such as this could be up.

    I don't know. How do I test?

    8.7 Volts at the Coil

    I have it but it's so confusing and hard to discern.

    8.7 Volts at the Coil

    At my wit's end with a boat. 1997 5.7L Vortec Mercruiser. 2 BBL carb. Thunderbolt V ignition. After doing a top end rebuild, it won't start...VERY weak spark that dies out immediately due to the low coil voltage of about 8.7 with key on and 6.5 while cranking. Batteries are both new and read...

    1995 Chaparral 2550 SX Refit and Restoration

    After a few weekends of leaving the boat in the water and using her, I had noticed that the drive and transom assembly paint was chipping further and the metal was corroding a tad bit. And so, I decided to clean, sand, clean, prime with zinc chromate, and paint the drive. I also wanted to...

    1995 Chaparral 2550 SX Refit and Restoration

    We also took her out the following day and she continued to run very well. Did a 50 mile cruise from Rhode River over to our home in Annapolis, before cruising almost the entire length of the Severn River and back. Seas were rough so we were really able to put her to the test. In the middle of...

    Unfortunately, we were not able to leave for the test run until late in the afternoon as I was tying up loose ends at the dock, but we did get out and put her through her paces and I am happy to report that she seemed to run really well! Here are some pictures of Saturday the 11th, 2020, the...

    Good question Ted! I believe the older Gen IV and Gen V 454s like this one are 10° BTDC. Whatever setting I set it to was on the engine cover.

    1995 Chaparral 2550 SX Refit and Restoration

    Well, guys I was able to paint the intake and get it back on. While I was at it, I installed all new belts, new impeller, new plugs and wires, new distributor cap and rotor, new fuel line from the tank, replaced the fuel filter, changed the oil and filter as well as the gear lube. She is all...

    1995 Chaparral 2550 SX Refit and Restoration

    The last few days have been very productive...I got the broken bolt out which was fortunately not flush with the block after taking the cylinder head off. I was able to twist it off with a pair of vise grips. After chasing the threads with a bolt, I then reinstalled the head and was able to get...

    Continuing on... A look inside the block water passages: Starboard side all cleaned up for re-installation (scraped and sanded): New Fel-Pro head gasket fitted: Anyone know what this loose pan under the intake manifold is??? Starboard head resting on dowel pins: Starboard...

    While waiting for the heads to be rebuilt and machined by the machine shop, I took the liberty to do the following: Enjoy the view at the marina LOL Design and order the new name! Fix a few gelcoat dings, inside and out. For example: Install a new proper drain plug. Despite...

    Nice, the 327 SSX is a nice boat. I had a client with one, but it was grossly underpowered with twin 5.7s. Only hit about 42-45 MPH tops.

    1995 Chaparral 2550 SX Refit and Restoration

    Not even close. The Chappy SX was a premium line for its era. It is comparable in quality with Cobalt and Formula, with three exceptions: the hull/deck joint is riveted which sucks, there is some sloppy glasswork in places, especially hidden areas, and also Chaparral did not do a good job...

    1995 Chaparral 2550 SX Refit and Restoration

    At this point, you may be wondering where is the need for a refit? Well, unbenownst to me the 7.4L Mercruiser (we came to learn) had a blown head gasket that was allowing a little bit of water into two starboard cylinders, causing a popping noise that occurered because water does not...

    This thread was originally posted on THT, but I'd like to share it here as well as I think this audience would appreciate it more. I think I'm done signing the praises of sterndrive pleasure boats to outboard cultists anyway :ROFLMAO:... Hello folks, here is my boat...she is a 1995 Chaparral...
