Hi Everyone,
First off i’m new to the board even though i’ve been browsing between here and a few other forums for a while. My name is Max, I live in Pompano beach, FL and I have an awesome 28′ WhiteWater with a cummins 6BTA 270 paired with a fixed surface drive. I recently upgraded about a year ago from my old 25′ Aquasport with outboard power and finally purchased my dream boat. This is my first Diesel boat, though my father has a 1969 Hatteras 45′ with twin Luggers and we’ve pretty much done or had everything done to these engines over the last 10 years.
My boat lived its entire life in the Bahamas only being used about 1 month every year and lived on dry-dock the rest of the time (until i purchased it) when i purchased the boat she ran great, but i knew i would run into a few issues being that it was not used regularly. (only had about 500 hours at the time of purchase) as soon as i got the boat home i drained the fuel tanks, changed the oil, all the filters and replaced the coolant and the impeller. the boat ran great and i took her to the Bahamas with no issues. about 2 months ago the boat began taking a really long time to hit boost and get up on plane, and now the boat will not hit boost at all or get up on plane. (ABSOLUTELY NO DARK SMOKE). She starts right up and runs perfect at low RPM and does not bog at all when i try to accelerate, it just hits a wall and stops accelerating. I went through everything with my limited mechanical abilities and checked the fuel solenoid, filters, fuel lines, racor, ran a direct fuel line from jerry can – eliminating fuel flow issues etc.
So here is the crappy part about all of this. I hired a mechanic after i could not find out the problem and he explained to me that i should change the injectors, i was planning on doing them soon anyways so i was fine with that. of course it did not fix the problem. next he recommended rebuilding the injection pump, i did so reluctantly and it did not fix the problem, although according to the company that did the job it was in poor condition. last and not least he was absolutely positive that the turbo was the issue (ill admit it was in pretty rough shape) but i was not getting dark smoke so i did not think so. either way i had the turbo rebuilt. of course this did not fix the problem. so now i’m $5,000 in the hole with replaced parts and my boat is still doing the exact same thing.
Needless to say my mechanic feels horrible and is not charging me any labor for the replacement of all these parts but that still does not help the fact that i dumped 5 grand into the boat and it did not fix my problem. I’m at the point where i have no idea what to do. he’s coming back with a bore scope to look at the lifters and valves etc but i have a feeling he might just be spinning his wheels.
if ANYONE has some advice to help me get my dream boat back up and running the way she would i would be thrilled.
i have a feeling it has to be something stupid but truthfully i have no idea
The only thing that has happened to the boat before this was that my exhaust coupler had a minor leak and was dripping right on the PTO shaft housing. this in turn was shooting small amounts of water onto the wiring harness and maybe elsewhere. this caused the harness to corrode and need to be replaced. none of this had any adverse effects on the performance of the boat.
PLEASE HELP ME I NEED TO GO FISHING BEFORE I LOOSE MY MIND!!
