Thanks Guys.

Im guessing the boat will be stored on the trailer, When you park it, take a jack, or lower the nose, throw a couple blocks under the end of the transom, then lift the nose of the trailer just enough to take the weight off the back, Your bunks end before the transom and if it sits that way for a while it can develope a hook in the bottom.

Very very very nice!

With regards to another stripe maybe something along the bottom of the side kinda like my old paint job??

Thanks or the info phragle. I was thinking the same thing when I first saw the trailer, so when we pulled the boat off the trailer I checked out the bottom of the boat and it's really straight. But doing what you're saying would ensure it wouldn't develop. Thanks 502ss, I was wanting to keep a simple paint job on this boat and not use any vinyl, but it's just a little plain I think. BTW, I like the way your boat turned out. And it looked nice originally! Here's a photo from the front. Those old dayton style axles were rebuilt in the last few years, and the surge brakes work great. They've kind of grown on me. They're so ugly they're almost cool...

Looking for ideas on where to mount my trans cooler line discharges. We were thinking maybe on the starboard side near the bilge discharge, so we would could look back and see it. But I don't know that that is necessary, out the back? Thoughts?
By the way, My engine guy has already broken in the cam on the port engine, so may be getting it this afternoon. Starboard may be wednesday or so. He still has to put it together.

hullofjustis 06-13-2014 11:53 AM

where is the water pick up, is part of the engine cooling or it goes right to the trans cooler from an external pick up? if it is only cooling the transmission i would have it come out on top of your out drive to keep that cool as well like a drive shower.

hblair 06-13-2014 12:39 PM

The water pickup for the transmisisons comes out of the sea water pump (I think thats what you call it)

hullofjustis 06-13-2014 03:41 PM

so it goes directly to the transmissions? if that is the case i would have it dump out on the drives however it is always a good way to tell if you are pumping water then you can see it.

hblair 06-14-2014 11:44 PM

Thanks, I'll have to get some thru hulls fittings for that. Meanwhile the port engine is back. The engine guy broke in the cam for me. We've gotta get all the hardware bolted to it and get it put back in the boat. The starboard engine oughta be back about wed-thurs. He had to replace all the bearings and the pistons due to the cam catastrophe. I was only able to spend less than an hour on the boat today, been real busy with work lately, by the way, I'm in the body shop business if you haven't guessed yet. I sealed the drain holes in the bilge with epoxy for the second time. I just want to be sure we don't get any more rot in the stringers or bulkheads later.
I'm still wondering about the paint. We havent painted the stripe on the right side. I'm seriously considering having no stripes on the hull...

Gh700xx 06-15-2014 09:51 AM

A little color to break it up would be good.

FASTTIMES 06-15-2014 11:10 AM

I vote no stripe!

ma454mike 06-15-2014 05:27 PM

I have a 1983 Scarab II Sounds like I have a similair set-up for the tranny cooler. Water comes from the sea-pump. As far as I know, my boat is all original. the water goes thru the tranny cooler and then dumps into the exhaust riser.

hullofjustis 06-16-2014 11:09 AM

i was thinking of cutting up small pieces of pvc pipe and tapping them in the drain holes and then 5200 them in place after putting resin around the wood. . what do you think?

hblair 06-17-2014 10:43 PM

If your using pvc pipe, you may be better off using epoxy instead of poly resin. I'm not sure about that.

Got the port engine put together tonight with some help from my nephew Trent. We plan to drop it in the boat tomorrow evening late. We'll see how it goes. Tentative splash date is now this Saturday. The other engine is being put together, hopefully have it by friday. Bought some edelbrock 1410 carburetors from Jegs, they're supposed to be here tomorrow. If everything falls into place like it rarely does, Saturday is the day.

hblair 06-18-2014 01:36 PM

Well, the carbs are here. Perhaps things are going to fall into place for a Saturday Splash?

These boats are easy to remove and install engines, only took like 20 minutes from starting to line up the boat, to having the engine sitting in place. Another hour and we'll prolly have the drive installed.

Running the port motor at 1500 rpm for 10 minutes to finish cam break in late last night. I think Shon was enjoying it. Click on the photo for the short video..

I assume the trannies are not in yet based on how far back the engines sit?

hblair 06-19-2014 11:43 PM

No the merctransII trannies are in there. You can see it bolted to the back of the engine in the first photo.

hblair 06-19-2014 11:45 PM

Or the port one is anyway, does your boat have the Borg Warner trannies? I think they are a little longer.

Yes mine has BW and they must be longer because my engines are almost a press fit! Your going to really enjoy that extra room in front of those engines!

hblair 06-20-2014 03:58 PM

Nice looking engine bay. Your motors are 565 hp? What kind of props are you running and what kind of speed have you seen?

hblair 06-21-2014 12:03 PM

It's looking good for making our launch today. Both engines in, drives on, tidying up here and there. If no big setbacks, we should see the water today...

We got her out yesterday and had some cutting out problems with the starboard motor but we were able to get that fixed. Boat ran good. Still got some things to address, the interior, stereo system, I have some decals being cut now, will replace gauges and paint the instrument panel prolly this winter. The boat is now useable. Here's a photo of my brother Brian (short hair) and Shon (long hair). I had them drop me off on a pier and I took the photo and video.

sounds nice in the video! must feel great!

hblair 06-24-2014 01:19 AM

Thanks guys. I like just hearing the thing idle around...
https://www.youtube.com/watch?v=Zqwy...iXxwInZZ6D0nSw

Yeah, we're glad to have the boat useable. Big sense of relief. We've been working hard on this thing for ten months.

Sunrocket24 06-24-2014 05:49 AM

Great work!! It looks and sounds great I still can't believe how fast you completed this project!

502ss 06-27-2014 05:47 PM

Awesome job! Glad to see another older scarab restored! Classic boats!

Gh700xx 06-28-2014 09:40 AM

wicked man looks and sounds

flashgordon 06-30-2014 08:33 PM

wow..i am totally impressed!!!!..what project...and u are doing it...wow...
i have never done anything near that big of project.
but i question , for anyone , is how is the top deck suppose to be attached to the hull??
in my bow are, about a 3 ft section,,hull and bow are lose from each other. i can see borken screws??
i am going to take off the rub rail and see what i have.
any advice would be great.....
was thinking of putting in bolts instead of screws, but dont know if i can get the inside to complete the assembly.
thanks..............

flashgordon 06-30-2014 09:06 PM

mine trans coolers are part of the total cooling system. i am not sure where the trans coolers r in the system, but i dont have separate dumps for trans cooler.
on current scarab or last scarab. i did replace these on last scarab, old ones looked pretty ruff.
but,,boat looks great.!!!!
sure wish i had ur skills!!

yes the top beck and bottom deck are supposed to be attached. thru bolt would be good and fiberglass the two would be the best assuming you don't need to tak a part anytime soon.

hblair 07-01-2014 12:11 PM

Thanks flashgordon, all the work we did except for the paint prep and painting can be done by anybody thats handy and motivated.(and has some equally motivated helpers) As hullofjustis said, the most durable way to attach the deck to the hull would be to bond it with polyester or epoxy, probably in addition to the screws. On my hull, from the cockpit aft, the rubrail had screws with funky little 4 sided nuts that were designed to dig into the glass and act as locknuts. Forward of the cockpit the rubrail and deck were held to the hull by self tapping coarse threaded screws that dig into the hull. We drilled almost all of these out and put new screws, washers and locknuts all the way around the hull, with the exception of about 5-10 screws that we couldn't get to, etc.

I still haven't run the trans cooler dump lines yet. I plan to do that soon.

flashgordon 07-02-2014 07:35 PM

[ATTACH=CONFIG]525636[/ATTACH]dump lines??? i dont get that,,as my trans coolers are in the cooling system..i think the water gets sucked in and ran thru trans cooler than up to motor.
i think thats the route..but i dont have separate dumps.
thanks advice and top decl to hull..
flash...............
i just went out to garage and look,,,water comes into sea strainer then into first cooler, then pumped in , is second coller, thern from there feeds up to the cam driven water pump. first cooler is pumped to trans, second is pumped with engine oil.
[ATTACH=CONFIG]525634[/ATTACH][ATTACH=CONFIG]525635[/ATTACH]
hope photos show up

hblair 07-03-2014 07:29 AM

Looks like you're system is a good bit different than mine

What we were talking about is a modification that helps the durability of the transmission in doing away with the spent cooling water "dump" into the exhaust manifold, and dumping the spent trans cooling water out the back of the boat, thru the transom or wherever. This helps the transmission to cool better because there is no back pressure pushing against the spent cooling water coming out. The water dumps out the back of the boat faster, therefore cooling the transmission better.
I have the merctransII transmissions and I plan to do this modification to my boat, but haven't gotten to it yet. 502ss has done this to his boat, he has the borg warner transmissions.

I hope this explains what we are talking about.

flashgordon 07-03-2014 03:23 PM

hmmm...i think i follow ,,but ok..what pump is going to drive water into trans cooler?? the sea pump?? are you going to y or t off the sea pump??
local speed marine shop i go to, guy commented to me yrsa ago, about the trans be at good running temp. i dont know the temp. he said this because i told him i was adding some big trans coolers to boat with the 502's i installed. similar is engine oil,,u want it at 210-215.
both my scarabs have/hard c-72's..
last scarab started out with c-71,,had them made into c-72's

hblair, or anyone, i am in the process of putting my scarab panther back together and there are some wiring at the transom that i have no clue what it goes too. green, yellow and black wires that have me scratching my head since i switched it from trs to bravo's i don't know if they went to the transmissions or what. the green wire looks like a ground.
