    Electric drive conversion

    My brother and I have a 1977 32' Luhrs with [cough-cough] twin Crusader 454's (model 350's). We get an absurd 1NMGP with this setup, and we are severely limited by our 140 gallon capacity. We have been considering a diesel conversion, but I cannot help but wonder about an electric conversion...

    NS8B Carburetor question...

    We were looking for a bit more power out of our 1998 NS8B, so I figured I would give the NS9.8B jets a shot. I saw a post somewhere else to swap out the slow jet, main jet, and main nozzle to un-de-tune it to a 9.8hp. I realize being an older motor, we may run into issues with running rich, but...

    Wrong thermostat....

    We have been doing everything we can to maximize our fuel efficiency (FloScan coming soon), and I am not sure if having the 143° t-stats is increasing our fuel consumption. Engine temps hold rock-solid around 145° all day long. I know in a fuel-injected car it can have an effect, but not sure...

    Raymarine L1250 Sonar Inop... ???

    Hey all, I've had the boat for about a year and a half now, and just last weekend at Catalina, the 600W transducer on my Raymarine L1250 stopped working. I still get a temperature reading, but the fishfinder shows nothing but red on the screen, and a constant depth reading of 150ft no matter...

    Edelbrock Performer Carbs on 454ci Model 350's? Possible?

    My brother and I want to ditch the Quadrabogs for some new carbs. I found the Edelbrock Performer #1410 (Marine) for a good deal brand new. Will these work on the Crusaders? Thanks in advance! Eric

    ... and the backfiring continues...

    This has been going on for several months now, and I am really starting to bang my head against the wall. My starboard Crusader RH 454 (Model 350, circa 1989-ish?) has been backfiring out the carb under load around 2500 RPM, or just about any RPM if the throttle is blipped quickly in neutral...

    UPDATE: Backfiring and starter bendix gear

    To those that were following this thread: http://www.marineengine.com/boat-forum/showthread.php?385737-What-a-day...-backfiring-( Sorry for the extra verbose story here, I have a tendency to elaborate. Here is the latest update: We were on vacation for a while, so could not get much done...

    What a day... backfiring :-(

    Just when it seemed we were getting all our gremlins exterminated, we took the Cheap Hooker out yesterday for a little inshore fishing. About four miles out, we decided to give her a WOT test. We hit JUST over 3k revs, then starboard started randomly popping out the carb. Back her down below 3k...

    Sealed fuel systems and vacuum...

    Just a thought, and curious if anybody has considered this before. These days, cars all have evaporative emissions controls (aka "evap" systems). What this does is draw a vacuum on the fuel tank, then the ECM/PCM monitors the vacuum. If the vacuum decreases faster than a pre-determined rate...

    Synch gauge inop at higher RPMs??

    ***EDIT: Ooops... there is an electrical forum. Should I delete this and repost there? I recently installed a new Faria Synch Gauge. If I am idling, it is nearly impossible to keep the gauge showing synched, but it seems to work properly. If port is at 800 and starboard at 1000, it points...

    Crusader Model 1996 350 Identification... help please

    We have had the boat for about six months now, and I want to get a manual for the engines. The survey said the engines were 1996, but the serial numbers were "not observed". I looked around for any markings, and the only numbers I was able to find/read were 14015445 on both; which I found to be...
