Default Awesome!

I have seen many discussions here on OSO about re-powering. I have seen people inquire about Mercs, Ilmors and other custome power.

In Powerboat Magazine (May 2008) they did an article about Raylars LSM550 aluminum engine. The 434cid closed cooled small block produces 550HP / 535 Ft punds of torque and wieghs only 543lbs!!! If you were replacing 2 GM big blocks you would save almost 1,000 lbs in weight!! Powerboat Mag says that the price is $26,873 and comes complete with headers.

Why isn't anyone talking about these motors?? If I was looking to power/repower my boat- I would give these a serious thought!

I think they are an awesome option, I would like to see how the weight saving has any effect on the center of gravity on other peoples boats.

I wouldn't hesitate to use Raylar's products based on the help he offers here in the tech section

I agree. I would "guess" that using 2 of these Raylar motors and saving 1,000lbs of weight would be the equivalent to having 700-800 HP motors that are normal weight. I am not an expert on this subject..anyone care to clarify this?

I have no connection to Raylar- I think they make a great product

There have been a couple threads on the subject. It is an awsome package! But it would be great to get some real world feedback.

Apparently this 292 has them. I sure would like to see a performance write-up on that rig!

It says 90mph, I think that is entirely possible. Wonder if Ray can fill us in?

BBC engines are about 800lbs. The weight savings might equal a couple mph. The weight savings is the about the same as running with 100 gallons less fuel. Maybe worth a couple mph.

It would be nice to see a side by side comparison vs the 525EFI's.

Griff, I was going on the #'s that Powerboat Mag suggested. However, Mercury Racing lists the HP 525 EFI at 1,152 lbs- The HP 700 SCi weighs 1,326 lbs! - (these weights are without the drives!!) The Raylar 550 is WAY LIGHTER

That is a bad azz engine. Maybe after some more guinea pigs report good results I'd take a closer look.

I would think the TQ curve would have a factor,but again the weight is a bunch of diff!!
