Tom & Marianella
"The Wet Spot"
Rigging is one reason. Engine machine work and proper dimensions for sustained marine use is another.
Stern drives. (unless #6's and 800 or less hp). Stern drives are maintance hogs and delicate. You don't see stern drives on too many commerical applications....
RPMS (ruins peoples motors). Sustained high rpms use. Pushrod valve trains don't like this.
Open cooling. Unless proper strained, crap(including salt) goes in your engine (see proper rigging).
Electrics. Electrics and water don't mix well. EFI has some merits, but I don't like sensors in the marine environment. Saving gas is useless if it breaks. Give me carbs and a mechanical fuel pump. Having an engine that vapor locks from the factory is a joke. Often marine engine builders have to select from the OEM efi parts bin, which often means emission controlled, and not intended for marine environment. Who has o2 sensors in their exhausts? May as well use a carb.
Government Regulations/Emissions. Anything mandated by these fools will decrease performace, increase cost, and break more often.
Variables. Shorting drives, stand off boxes, props. You start playing with these and water pressure and rpm changes. Now you are in the R&D business. Drive dimensions are not standard (relative to the hull) so the builder or the owner of the boat has to optimize his own.
Because you just can't get out and walk away.
Q- Uncle Dave,,why do you have 2 boats?
A-Because with 2 boats I have a 50/50 chance of actually going boating!
A lot of it is environmental- mixing water with anything is a game changer.
A lot of it is the stress factor on boats and engines, and the fact they aren't used in regular duty cycles and tend to sit- then be abused.
A lot of it is guys not knowing what they are doing and trying to build things to go fast.
sooo.....Would we be a lot better off with more and different players- I dont think so. I think we'd have the same problems and need to get parts from different places.
Honda does build a "boat"- its a small one called the aquatrax and I see them broken all the time. Well its a jestki thing.
Yamaha builds full size boats- towed one to the ramp a month ago- it was sinking for some reason.
Sea doo/bombardier builds wakeboard boats - see them broken all the time.
Most autos dont have 300HP much less the 5,6,7,8 ,9 & 1000+ we have in boats.
Even if toyota built a boat it would need an impeller - will that go out in a year of neglect, or misuse, or dry start by your teenager in the garage - you bet.
It is what it is my friend.
Toyota did a marine engine for a couple years. It was in ski boats I think. It sucked, over complicated and broke a lot.
