Baller MAD11 Posted November 11, 2013 Baller Share Posted November 11, 2013 @dw Dart blocks not a bad call, but certainly not cheap. I do have a few raised cam versions sitting in the shop. 632ci probably a little much for a ski boat though so we can't use the cranks I have. Have to shorten them up a bit. I never thought about ski boat with a set of my Big Chief heads onboard. Man this has me thinking fun stuff. Link to comment Share on other sites More sharing options...
Baller SkiJay Posted November 11, 2013 Baller Share Posted November 11, 2013 Whatever the final solution is, I hope it's a V8. I'm actually afraid that a boosted I4 or V6 will be the response because they seem logical on nearly every front. I worry that sound is too low of a priority. If I'm going to spend hours upon hours in a boat, please let me listen to a big warm V8 or the silence of electric. The thought of skiboats sounding like little inboard/outboard runabouts gives me bitter beer face. Link to comment Share on other sites More sharing options...
Baller ForrestGump Posted November 11, 2013 Baller Share Posted November 11, 2013 Dart already makes a 5.7 small chevy block. But in the limited production they make them in, the block alone is $1500. Link to comment Share on other sites More sharing options...
Baller oldjeep Posted November 11, 2013 Baller Share Posted November 11, 2013 Likely that someone will just buy the tooling and continue casting them in Mexico Link to comment Share on other sites More sharing options...
Baller Ham_Wallace Posted November 14, 2013 Baller Share Posted November 14, 2013 If you must bolt something to an engine to make it run......you don't have enough cubic inches! No replacement for displacement! Link to comment Share on other sites More sharing options...
Baller eleeski Posted November 14, 2013 Baller Share Posted November 14, 2013 @Ham_Wallace You are already bolting something to the engine, a geared transmission. Since HP=torque X rpm, if you have plenty of horsepower, all you need is to adjust the rpms with gearing to get the torque desired. No substitute for proper gearing! Kirk has a little Ninja motorcycle. It is quiet, light and fun. But gutless in the wrong gear. If I ride the tach with an auto or boat mentality it is a dog. If I ignore the tach and ride what feels right it is sweet. The tach may be two or three times what I am used to but that's what the engine was designed for. I hope that ZO can cope with different power curves and still give the same feel. That is the real challenge. Eric Link to comment Share on other sites More sharing options...
Baller Ham_Wallace Posted November 14, 2013 Baller Share Posted November 14, 2013 No geared transmission here. 1:1, 6.0 litre, 405 HP, Great fuel economy, no problems. Link to comment Share on other sites More sharing options...
Baller eleeski Posted November 15, 2013 Baller Share Posted November 15, 2013 @Ham_Wallace 405HP? You must be a jumper! Link to comment Share on other sites More sharing options...
Baller_ DW Posted November 15, 2013 Baller_ Share Posted November 15, 2013 Remember when 240-265 hp was enough! Engine development is a wonderful thing... Link to comment Share on other sites More sharing options...
Baller eleeski Posted November 15, 2013 Baller Share Posted November 15, 2013 @DW My 250HP American Skier weighed a LOT less and had a nice low drag hull. And jumpers were less dependent on massive boat horsepower. The new engines are pretty cool - small, lightweight and lots of horsepower. Maybe Indmar will develop a real winner with the new engines.

Baller_ DW Posted November 17, 2013 Baller_ Share Posted November 17, 2013 @Eric: weight certainly has a big impact, the 2500# boats didn't require the power of the newer variants that tip the scales at over 3000# and have a lot of wetted surface area.

Baller skiinxs Posted November 17, 2013 Baller Share Posted November 17, 2013 Exactly, wouldn't it be nice to take a 2900 lb boat down to 2600 lbs simply be switching to a lighter, more powerful engine. Link to comment Share on other sites More sharing options...
Baller_ DW Posted November 17, 2013 Baller_ Share Posted November 17, 2013 @skiinxs: It makes quite a difference, I lopped off 300# on a 2600# boat. Does a nice job of flattening the wake. Weight at the transom has a larger effect, but it all helps. Link to comment Share on other sites More sharing options...
Baller Wayne Posted November 17, 2013 Baller Share Posted November 17, 2013 A coworker has a SN196 with a supercharged Ford 5.4 liter (F-150 Lightning engine). They built a couple when ski fly was getting some legs. I think his is 1 of 2 still running and floating. The heat exchanger for the supercharger is a closed cooling system and the marinization has some issues leading to water in the air stream (mainly condensation build up with out a proper automatic draining system). He used to work for ford during the modular engine boom and had input on the lightning engine. For a marine environment and after having a boosted marine engine he would rather not have the complexity. The power is great but a naturally aspirated package with its simplicity would give him more hours of ski time with less maintenance/upkeep time (his words).

Baller Ed_Obermeier Posted November 17, 2013 Baller Share Posted November 17, 2013 Exactly. Why make it any more complex and costly than it really has to be. Simpler is (almost) always better. They've already priced the majority out of the new boat market as is, more complex and pricier engines will only price even more of us out of the market. Someone somewhere will continue to produce old school small blocks. It already works, no need to fix it IMO. Link to comment Share on other sites More sharing options...
inland Posted November 17, 2013 Share Posted November 17, 2013 I'm pretty happy to see Ford back in the marine game. I'm a Ford guy at heart however I hate to see the SBC go away from the marine market. Link to comment Share on other sites More sharing options...
Baller gregy Posted November 21, 2013 Baller Share Posted November 21, 2013 We've got a 06 Jeep Commander with Dodge 5.9 Hemi. That thing is a rocket. I think that engine would make a great inboard engine. Link to comment Share on other sites More sharing options...
