    Default Lots of questions on a daycruiser . . . enclosed engine

    Spent the last couple days searching but i guess all mine was to vague or something . . . here is a list of ??'s i have

    Must i use marine parts with an enclosed engine ???

    What parts would those be ??

    Does the short (not the very short 1") spark arrestor flow decent for a bbc that is basically stock with flat tops and hyd cam and a 750 ?? (im into a clearance issue and have just the room for those)

    What hinges and hatch prop do you use ??? Do you have any pics of the hatch open ??

    If im running a decent sized stereo i should run two batteries ??

    Any more info you can pass along on a daycruiser type enclosed engine please do . . this is my first boat of this type . .im used to let'n it all hang out !!!

    Recommended and actually "required" as far I know . a Marine approved Carb, A Marine alternator and Marine starter as well as Marine approved ignition . We're currently restoring a open bow Wreidt . none of this existed Prior! The replacements Consist of: A 750 Holley dfdp Marine carb (it had a auto type Vac secondary carb ) A Mallory electronic marine dizzy (had automotive points type with vac advance) A marine certified Alternator (screend) and Marine starter etc The Flame arrestor (plenty of "breathing" for a BBC ) has a "fume tube" to link to the Holley Marine electic pump. Could you "get by" with the others? probably but not recommended ! Although this Marine approved parts clearly added to the cost of this job surprizingly the difference calculates to around $500 (job cost well over 10k) This boat (covered engine) incidentally also had no bilge blower system . Obviously the risk of spark and or bilge explosion are much greater in a covered engine environments why take a chance? The "complaint" heard is usually "why should I pay extra for the mfg to simply say something is marine approved?" To me its all about safety and responsibility, let us know if we can help Tom

    BTW all my boats run dual batteries systems with the capability of A,B,A&B or off capability "redundancy" is a good thing in that category IMO Keeps one from getting stranded too

    All the following must be coast guard approved I believe.

    Carb
    distributor
    fume feedback tube from flame arrestor to fuel pump
    fuel pump
    bilge blower (2) I think this is true in ca
    Alternator

    typically with an enclosed compartment you will also need an oil cooler

    Marine parts are great for safety but you can live without depending whats needed. Mounts,arrestor,fuel pump,carb,fan/blower....
    Not sure about the short arrestor but I modified my hatch to fit regular size one and added a little space for taller intake down the road.
    I went on ebay and bought some hatch hinges (25 bucks). I made my boat interior last year and make sure you shop for the look and fit.
    The lift I have is manual piston type. If you have the time and extra cash...electric is kool.
    I run two 29 batts with perko switch. I have two amps,two subs,four seperates, two drive in speakers and a wake tower with four seperates.


    I remade the under part of the hatch.

    thanks for the quick replies . . im not so much trying to look good on paper . . the lake cops here dont know what to check and will be glad im in this and not running the other boat with zoomies !!!

    If i have to modify the hatch for the intake i will do something differnt such as a scoop or just an engine cover only and the two little seats back there . . but im really set on a flat complete cover . . .
    I just found some cool hinges on cpperformance doing a yahoo for engine hatch hinges . . they seem to come out and up . . . the dork before me had three door hinges and it got too close to the glass before coming up so it was spaced with washers . . . how well do those gas charged shocks work . . i was thinking of playing with something like that for now until i can afford something elec or hyd .

    are the marine starter and alt spark proof or water proof or both, what makes them special ???

    My hatch has a cut out just for carb. I made the scoop out of a couple pieces of wood and a t-shirt. fiberglassed and then covered.
    I bought my gas shocks from rex marine. I have two sets depending on weight. If I want them to calapse easy, the lesser lb one and so forth.
    Measure your mounting spots when closed if poss(10-12inch)...17 inch or 20 inch max open. You can ask the sales person for info on part and install to get the right ones.
    Not sure on the starter but mine says marine..the alt just has a screen on the back, like a arrestor. The unit itself is normal except the cover on the back.

    Not water proof but spark resistant so you don't blow your hatch to the moon if inclosed engine compartment becomes saturated with fuel fumes. Screens built into the vents on starter, alternator and distributor keep the spark suppressed.

    Default Enclosed engine=marine parts

    Many of us get away with using automotive parts (including me), But I would think that with an enclosed motor there is even more reason for marine parts as there is less excape path for flammable fumes. Dont know this for sure but makes sense to me.
    Boating is nothing like cocaine, boating is much more addictive and results in bigger parties!
