Engine Mechanical / Electrical / Carb issues
« on: October 02, 2017, 04:35:02 PM »
Hey everyone just wanna get ur guys opinions, rebuilt 454 this season, carb got rebuilt as well, (3rd time this season, twice now since motor rebuild) went on test drive Friday with mechanics boat runs   perfect for 2 hours, turns off 25-30 times, fires right up all good, put on trailer take down street to campground launch it n it barely starts n runs like its flooded. SzALWAYS. Does it after sitting 20/30 min after being warmed up, they take carb apart say needs rebuild, jets n carb clogged? We're starting to think there's a internal leak we can't see? Slowly leaks n floods over 20 min? Any help appreciated.. Holley single pumper 650(maybe 600) but single pumper

Engine Mechanical / Electrical / 454 compression test
« on: July 25, 2017, 11:31:33 AM »
So after my BBC stock original 454 not running right we just did a compression test, #5 read at 87-90 and the rest were in between 110-120, so I'm told I need a valve job, my main question is is it not smart to just do a valve job and not rebuild the rest of the motor? It's a stock 454 and at this time I'm not trying to have anything other than reliable nice cruiser.. trying not to break bank but also don't want to regret not doing something when it was torn apart in 6 months... also ballpark what am I looking at for shop like very basic ballpark, $1k, 2k  more? Less? Thanks guys I appreciate it very much

Engine Mechanical / Electrical / BBC hesitates but never dies
« on: July 06, 2017, 10:01:51 PM »
Just got on the water today ran good for 30 min or so then started hesitating little bit but never died n kinda thought it worked itself out but then pulled into no wake zone, let off the gas and it was still prob around 2000-2500 rpm, (tach isn't working, getting new gauges n couple weeks) but it was keeping me going bout 10-12mph without me on throttle at all, so I hit the throttle kinda hard and it idled down a bit but still was revving higher than normal for sure, by then I got to my spot but curious what u guys think, it was really acting as if it had the choke engaged still but idk... I'm thinking carb needs adjusting? It's a Holley 750 thank u guys for ur advice...

Hey everyone! So over the off season we had tons of work done, new interior, stereo, motor got pulled, new jet, new transom, new msd ignition system to replace Mallory, motor went back in no upgrades just pulled out serviced put back in, after working out few kinks boats running great but last trip at havasu motor temp would jump 20 degrees almost immediately after pulling into no wake zone after a 20 min cruise at like 45 mph not floored it by any means... even before all the work, gauge always has motor running at 135-140 which I thought is cool so at the no wake zone it jumped to 160 immediately so I opened the hatch and it seemed to cool back off, should I b concerned it runs so cool? Maybe faulty gauge? I am having issues with other gauges, speedo n tach went out last trip, speedo always been temperamental and I had em replace the speedo mechanism on the transom still nothing... thanks for all your help guys! I'll post pics of all the upgrades later today!

Engine Mechanical / Electrical / 454 intake manifold
« on: September 23, 2016, 09:34:01 PM »
Hey guys, so u may or may not have seen my last post about 454 won't stay running, idles then shuts off, got it fixed, gs said o ring in jet, my big question is, my mechanic (yes he works on my classic truck not boat) but he's good mechanic lol... He took my carb apart before I took it to gs and he said a big problem is my intake manifold doesn't match my carb, I'm not a mechanic so doin my best to describe it, there's a spacer in between my carb and intake manifold, it's like an inch thick or so, and the holes in the stock spacer or bracket don't line up perfect to the holes in the bottom of my carb, I can see it pretty easily but it's been set up like this for long time according to old owner and I honestly believe him 100%... But mechanic is saying its starving for air, cause spacer holes don't line up n I need new manifold.. My question if this makes sense is do u guys agree or no with my mechanic??

Bought my boat month ago, gs marine tuned up n went thru it, it was sitting for 2 years, so I drained what gas I could, there was less than 1/4 tank in both tanks, filled up new 91 went to puddingstone last Monday it ran great no issues at all, get to Parker today and it won't stay running, acts like not getting fuel, gs just completely rebuilt carb, single pumper dual feed... Help!! At foxs if any mechanics out here! Pm me! So we do a few tests, we take off the hose on bottom of fuel pump,(mechanical) and to my understanding, the hose should b lower than the tanks, so should pour gas out right? No has comes out, just tiny bit..
