Unhappy with my Boat

The ford has (1) bigger stroke at 3.74 to the gm 3.62 which will give more torque at any given rpm, (2) due to the OHC has wider bore spacing for larger valves and less moving parts for lower friction, (3) more liniear torque with OHC with more optimum fuel and spark control and valve position in the heads.
On a side note NHRA is been having a fit trying to figure out how to come up with good classes for the CobraJet fords which are 5.0l that are destroying the COPO Camaro 6.2 l and 6.4l Hemi , look Ive been a Big Three guy for years with my share of Corvettes but Ford invested heavyly in engine technolgy and it shows , look at the fuel economy numbers with the Indmar Raptor we cant believe what were seeing at our events.

Fair enough, I don't share the same opinion though. 1-I've always preferred shorter stroke to allow a better rod ratio in the same compact package. 2-Larger bore centers won't allow for bigger valves, the cylinder bore & valve angle are the limiting factors. Valve train friction is very difficult to quantify on the whole because the valves closing off set the power required to open the others. 3-Ford went to dual spark to clean up emissions regardless of what the marketing says.

As someone who works on all of these engines in multiple installations, I really appreciate the compact, easy to work on nature of the LS series engines. I can still swap spark plugs in a 6.2L DI engine in roughly 20 minutes with common hand tools, how long on the Ford? The other thing that sticks in my craw is the fuel economy thing, I have yet to see a true apples to apples comparison with the same prop. The current standard 2419 vs the older popular 1235 would be like putting identical trucks in front of an 8,000 lb trailer-one with 4.10 gears, the other with 3.45-can you tell me which would be more efficient?

As to the bore centers being wider , what I was saying was with the push rod gone you can get a better valve lay out in the head and you still have some deflection from the liffter to the rocker in an internal cam which is not as precise as OHC , the block is stronger when there is more thickness between clynders , as to the prop , I agree with the apples to apples comparison , however Indmar has been running the GM engines since 1993 and never spec a different prop other then the 1235, I suspect each engine torque tested optimun with those prop specs , as to the rod ratio 3.74 is still a short stroke IMO just like my 1968 vette 427 it had a 3.76 stroke and was high reving motor , and at this point I havent seen any 6.2l ford engine problems , our boat haulers to our dealership have several thousand miles on them with no issues at this time.
I can say this when Nautique ran the Ford GT40 engines and the Excaliber 350 GM in the same years I could tell which engine was in the boat without seeing them , the Ford had much more low end pull and was more solid when I was cutting on my ski, but this is what is good about having a varity of choices everybody can have what they like.

That's cool, glad to hear more than just the marketing hype.

For the record, I don't think the Ford is a bad engine-not necessarily worse than the GM LS series, but not better either. After all, how many versions (2V, 3V, 4V, BOSS/Katrina & now Coyote) have they had since the LS was released? Gen IV basically added DOD & Gen V is going to GDI on the same basic architecture. I'm all for the advancement of technology, but a guy needs a chance to lean on something before making drastic changes-kind of like boats, makes you wonder how much testing is actually done before releasing to the public.

New Update still no boat all the parts are in but they keep finding new problems everyday it seams like now they are saying the motor mounts where not lined up at the factory and there working on that.

That sucks to hear, worst time to have major problems with a seasonal toy

Unhappy with my Boat

It pisses me off to no end. The people at Tige know how I feel about it also. I usually get a new boat ever few years and this is my last Tige. Boat looks great and has a great surf wave but I'm done.

I don't blame ya man. There's certainly no excuse to have alignment issues with the motor and it's mounts. I can tolerate some QC issues.... every wake boat company has them but major mechanical stuff or stuff like this would light my fire too.

[talltigeguy]

That's not to say that the motor left the factory crooked. Having had a questionable dealer work on the boat previously, you never know. At least that is probably what corporate is going to say.

I am not a mechanic, but an alignment job always has to be done when the tranny is replaced, right? I am not sure how this really adds much time to the repair.

EDIT: Are they saying the motor cannot be aligned at all, because the mounts were not installed properly? Hmmmm....does that explain why the tranny went out in the first place?

That does not get Gibbs back on the water, but I do hope that this gets resolved quickly.

Got the boat back tonight. New Vdrive, transmission and everything back lined up.ImageUploadedByTapatalk1435896313.580072.jpg

Glad to hear, hope you have some fun on that thing now. Did they have to move or modify the engine mounts?

[007]

Good to hear! Hope you get to enjoy some trouble free time with it!

That's awesome! Glad to see the dealer had a major issue resolved in about a week. Now go enjoy! Have a fun and safe 4th weekend!

[gibbs114]

Told me that two of the engine mounts where left loose at the factory. The dealer used the term realign. Glad to have the boat back but now it's gonna rain everyday here.

Don't let the rain stop you after all that!!

[gibbs114]

Took the boat out today and guess what. Not fixed doing the same thing as before. Beyond pissed don't ever know what to do next.
