Agreed - it's there.

Per earlier suggestion, will just Tee into fuel line to check fuel pressure supply. That eliminates the pump.

I can rev engine, on the hose with no load, past 3200rpm (ie no load, lower fuel requirements).

Good thought... the cam lobe, however, is protected by part #16, a wear ring, which all parts look fine.

Wear ring on the pump cam shaft lobe looked fine. No pitting, scuffing, etc. Looks like normal camshaft operation.

Guys,

Need a little advice - first, the back ground.

Twin carbed HP500s. Port engine running fine. Starboard this year, had seal in belt driven water/ fuel pump go out. While rebuilding,...

Have a Merc one and dipstick/tube for sale.

mods - please remove thread until I get it on OSO. apolgies

Removed - need to post on OSO first

Any tips on how to get the vert shaft nut off and hold the shaft at same time? I know Merc has a "special tool" for that, too.., Guess I could temporarily reinstall drive and have boat in gear to...

thanks, Smitty - was hopin you'd weigh in on this topic...

Guys,

Did a search and not coming up w/ anything. Looking for a cross reference on Merc bearing part numbers for a bravo lower.

Thanks

Thanks for the info,Carder. Just like everyone else, I would like more top end speed. I knew mid-range/ planning would improve. Didn't know if the performance effects from an extra blade/less...

Apologies... my mistake. They are turning IN.

Speed is 84.3mph GPS, fall/spring, cool, day, me, no fuel. Otherwise, 80-ish.

Any feedback on how these props might perform?

Guys,

Where do you find the screw-mounted, rubber grommets that install on the underside of engine hatches? They are the ones that act as buffers between the engine hatch and the deck when...

Thanks for the advice, Randy. I might explore different props but leave the X-dim alone. Summer heat and humidity here drops engine RPMs to 5-5100. Fall and spring, the boat still turns 5400.
...

So, I have researched quite a bit and found several sources that claim a 30P Bravo I prop is more like a 28P, maybe 29P on a good day. That would seem to be supported by those boats that drop 2...

With the slip numbers my boat is seeing, should I start off with 1/2" spacers or jump right in with 1"?

I am awaiting my 30P labbed Bravo and IMCO Extreme prop shaft to get boat back on the water...

Monstaaa,

Great reply! So, given what you have said, what are the changes needed to install 1" spacers? I would assume it entails a different length vertical shaft as well (come with the kit)?
...

The engines were gone through at the time of the Crane valve spring update (a problem everyone has heard about) The only thing that wasn't swapped was the exhaust.

Dyno sheets show 620hp at...

Ragged,

Are those gps speeds? I didn't think I was off at all. The all- stock boat specs at 77-80 mph, I believe. Throw in another ~60hp = +3 mph (a stock hp500 is rated at the prop, so they...

Also, should I go ahead and upgrade to 1 1/4" shaft? Does it fit all the standard bravo internals in my -2" shorty without changes (ie just the splined dia. of the prop shaft that is external to the...

WOW Carder! 88mph rocks on 29QIV's... would be a good start and labbing should pick up 200rpm and 1-2 mph, correct? Is that possible to hit close to 90mph with just those changes? Then again, 31P...

Guys,

Have the lucky "opportunity" to select new props due to losing a prop shaft and prop running over the weekend in our river. Anyone have some first hand knowledge, not just a give this a try...
