Took the boat to pyramid yesterday and it was acting up. Seemed to me like lack of fuel.
Its a 74 spectra v-drive with a 454 chevy, holley 750 DP and mechanical holley fuel pump. The first time at Castaic it seemed to run great but I was just cruising around, thought I felt it lag a few times after running at WOT for a quick burst, but couldn't tell cuz it was windier then shyt. This weekend was dragging around some tubers at about 2000 rpm and it started slowing down, not stopping just slowing, so I put my foot into it and the engine would almost die. I would take my foot off it and it would catch and continue running rough. Later in the day I was idiling around for 5-10 mins and decided to take off, about halfway onto plane it started acting sluggish and started slowing down, put my foot into it and it started to cut out, took my foot off of it and let it idle for a couple more minutes. Then took off again and it was fine, cruised the lake twice with no problems, kept my foot out of it tho.
So that's what I got goin on and lookin for advice. I ordered a fuel pressure gauge so I can see what, if anything its reading at certain times.
My dad had a similar problem which was when he ran WOT the fuel pump couldn't keep up and essentially had no fuel pressure showing on the gauge. He installed an electric fuel pump and that solved the problem. He has the same engine/carb/fuel pump setup but its a jet
Im replacing the 1/4" hardline running from the pump to the carb with 3/8 and replacing the fuel filter.
Wondering if theres anything else I could check before the fuel pressure gauge arrives, or if you got any other suggestions?
Thanks guys
