X3!!  Presuming adequate clearance for all engine positions and sufficient radius for the hoses that looks ideal to me!!

Completely random idea , but regarding the drilling of new holes in the transom, would it not be possible to fab or find some sturdy clips/hooks and actually bolt them underneath two of the existing engine mount bolts like glorified washers since the lower backing plates on the transom line up with the main horizontal cabling run perfectly??  I guess I'm envisioning something kinda like the flexible wire harness clips that mount like washers underneath some of the bolts on outboard powerheads to keep coil wires and other parts of the harness in proper alignment.  Feel free to immediately disregard...  


...and btw - I just can't WAIT to tackle mine....   It's gonna be interesting with cabling going to both Port and Starboard sides.

Man...oh man....  

EXACTLY what we had in mind Bob :flower:

GREAT JOB  

PS...can the fuel bulbs go in the box?

Thanks!!

PS...can the fuel bulbs go in the box?

Ummm...... well there may be some CG reg that says NO and piston heads like the primer bulb to have that upward slope to it (there's a thread here somewhere) like the original layout, still........

The bulbs last longer out of the UV but it would be tricky to get that slope. Distance would be greater from the engines but that might not be a deal breaker. Fitz could give ya the skinny on performance, SB on the regs.

I know for a fact about UV.

Good luck.

CB, the dumass that rigged Miss Marco had the primer bulbs in the console laying on the batts

Well they got that part right cause it wasn't burnt to the waterline when you got it.

Here's one link to about 10 pages on "primer bulbs".

I'd say you could mount below Scott. The slope might be a challenge but then what hasn't been.

Good luck.

Wow!  That looks bitchin'  rigging V2.0 looks sweet!  

I think the no primer bulb in the hull rule is for inboard motors.  If they do go in the box you have to be able to mount them vertical or be able to hold them vertical so the check valves will work.

Perfect Bob... As for the primer bulbs, I think they'll do fine in the box, think about all the six gallon tanks we've run with bulb laying on the tank, pointing down,up, laying in the bottom of the boat in bilge water.etc without ever having an issue for fuel delivery.

In regards to primer bulbs, first, I/Os and I/Bs?  Not a concern, as they have mechanically driven fuel pumps similar to automobiles, no need for primer bulbs (ever seen an I/O with a primer bulb?)...

In regards to placement, CG and ABYC haven't stated opinions on location, they treat them as part of the boat's fuel system, i.e. hoses/lines,  just as long as the placement of fuel primer bulbs meets the same requirements in regards to proximity to batteries and battery spaces.  That's really the driver when it comes to routing fuel hoses and lines.

However, manufacturers tend to get picky about bulb orentation, especially Yamaha.  They want the arrow pointed up (and I believe some others have stated the same, although I think it's a bunch of bullchit...).  Personally, having been rigging motors for a few years now, I have seen primer bulb quality degrade over the last 20 years.  At Wellcraft/Aquasport, 17 years ago, we built thousands of boats a year, we used nothing but OMC primer bulbs, regardless of engine type, we rigged them in all sorts of different fashions (but NEVER with the arrow straight up or down, always a relatively sideways install), and didn't here a peep from either engine manufacturers nor customers in regards to orientation of the bulbs causing fuel starvation issues, collapsed lines, none of the stuff you hear about today.  I have never liked Yam bulbs, Suzuki bulbs, I feel Quicksilver (Merc) are just a little step above the aforementioned 2, as they all felt, in comparison to OMC...cheap.  Flimsy.  Not of the same durability.  I'll be picking up (2) OMC (now BRP) bulbs for Scott's boat.  It's what I know works...

Scott, yes the bulbs can be installed in the aft box, no problem.  That's where you want them, that's where they'll go...

Ryan,
Have actually done many a twin where the rigging enters per each side of the motor...starboard on the starboard side, port on port.  The key is to make them mirror images of each other on the rigging you can control, i.e. engine harnesses, batt cables, water pressure, maybe fuel.  The "problem" is the shift and throttle cables...they are ALWAYS the challenge on older motors where they enter the lower pan opposite from the other rigging.

Of course, we could all ditch these older motors and go with Verados, FBW, no cables!!

I don't think the orientation of the bulb will matter for running.  Having the arrow pointing up only matter when priming a dry fuel system.  Air alone is not enough to make the check valves open and close properly.  I didn't believe it until I primed my motor one day while holding the arrow pointed up.  It primed much faster!

[Callyb]

Now that's what we're talking about right there :!:      

Excellent job :!:

[seabob4]

OK Scott, here's the starboard side (port side cut and ground as well) under gunnel glass cut out, and some grinding done...



This pic was taken on my back, looking at that area the same way I cut and ground...in my face!  Your bill just went up!! Haven't itched for quite some time...

Anyway, that's what you have.  PLEASE make the speaker enclosures no more than 12" long TOTAL, as the areas I cut are 13" (based on the Bose dimension).

Bruce,
I know people with "newer" motors, circa '08 and later, that prime their motors once a season and that's it.  While I do believe that orientation will make for a faster prime (as you proved), I don't feel it is necessary for the motor to run properly at all speeds, idle to WOT.

What I DO think has taken place over the recent years is an overall degradation in quality of the components, just as we see with virtually any other product that we deal with on a day to day basis...

Great job Bob!  Why not put the bulbs in the same place you had them on the first rigging attempt?  

Scotty, the tortoise is approaching the finish line.

looks awesome bob!!!
